Comment:

 It's likely that this has been caused by #55926.

 Recompiling with `cxx11 1.1` and adding `-stdlib=c++11` causes other
 corruption:

Comment (by Ionic):

 Switching to a `libc++`-based installation as described in
 [[LibcxxOnOlderSystems]] fixes this bug, which is not very surprising.

 Given that boost seems to be linking against the system `libstdc++`, which
 doesn't support C++11, we could potentially fix this issue by having boost
 link against `macports-libstdc++`, which does support C++11, if the
 `libc++` is set to `libstdc++`. Comments?

Comment (by kencu):

 We are about to default to `libc++` on all Intel systems, in part for
 exactly this reason.

 Perhaps this is a `wontfix`?

 Yeah, that's why I decided to switch my 10.6 VM over to the new system.
 There are more and more problems with the default system `libstdc++` and
 if consensus is to only support these systems with `libc++`, I might as
 well switch.

 > Perhaps this is a `wontfix`?

 Maybe. The question, though, is, whether adding `-stdlib=macports-
 libstdc++` to the boost build process if `cxx_stdlib eq libstdc++` could
 trivially fix this problem for the now legacy-legacy platform or not. I
 might want to test this out in my `libstdc++` backup prefix.

 textproc/source-highlight: use cxx-1.1 PortGroup, force stdlib selection,
 revbump.

 This selects the right compiler and stdlib, which is especially
 important on older systems that need to use our stdlib based on a newer
 GCC version that provides proper C++11 support.

 Since libtool is picky about compiler flags and likes to strip unknown
 flags out, force the stdlib selection to have libsource-highlight link
 against the correct stdlib (incidentally also the one that boost was
 built against).

 That does surprise me. That should not have worked, since that works by
 passing the `-stdlib=libc++` flag every time C++ files are compiled or
 linked. Since that flag was missing when linking, linking should have
 failed. And it should have succeeded when ''not'' using
 LibcxxOnOlderSystems.

 Since #55926 was fixed, on older systems, boost does ''not'' use the
 system libstdc++, which doesn't support C++11. It uses the MacPorts
 libstdc++, which does support C++11.

 Replying to [comment:4 kencu]:
 > Perhaps this is a `wontfix`?

 No, we should fix such problems by passing the `-stdlib=` flag where
 needed. This will continue to be necessary after we make libc++ the
 default cxx_stdlib, unless we change the clang compiler's default stdlib.
 I know you've advocated for that elsewhere so we don't need to discuss it
 again in this ticket.

 Using the cxx11 1.1 portgroup should not be necessary. The whole point of
 #55926 was to make C++11 features ''available'' to ports that use boost,
 but not to ''require'' ports that use boost to use C++11. If that didn't
 work for source-highlight -- if source-highlight doesn't build on older
 systems anymore unless C++11 is used now -- then we might need to
 reevaluate what we did in the boost port for #55926.

 Sorry, of course I meant `stdlib=libc++`.

 As far as I've seen, source-highlight's dylib was linked against the
 system `libstdc++`. That's also visible in the crash report. I think the
 problem here is that the binary and library are built and linked against a
 different stdlib instead of the one found in library dependents (like the
 boost-regex library). Since two different C++ standard libraries are
 linked in this case, a lot of stuff breaks. If we build programs like
 `source-highlight` in C++11 mode and against the same stdlib as boost,
 such mismatched should not happen.

 That's correct, not sure where I got that idea from. It was linking
 against a libstdc++ version, but it was not the system one, but (the
 correct) MacPorts version.

 I know you've advocated for that elsewhere so we don't need to discuss it
 again in this ticket.

 If doing the migration correctly by changing `cxx_stdlib` and forcing all
 usage of C++ code to be linked against this, such problems shouldn't come
 up any longer (unless we start mixing up `libc++` and `libstdc++`, but I
 hope there's no reason for this to happen).

 It definitely didn't work. `source-highlight` was both linking against the
 system `libstdc++` and pulling in `libboost-regex-mt.dylib`, which linked
 against a different C++ stdlib. That lead to everything crashing. Only
 force-enabling C++11 mode and changing the stdlib at compile/link time
 directly to the one `boost` was built against fixed this issue.

 I do not see a way to fix such library mix up issues just by having boost
 build against a different stdlib. Other programs will always be linked
 against the default stdlib (if not specified otherwise) by the compiler.
 The only way this could *possibly* work is by using `-nostdlib` which
 avoids pulling in an stdlib - and hope that library dependencies will pull
 in a suitable stdlib. I don't know if programs and libraries will
 successfully link at build time with `-nostdlib`, though.
