Created attachment 563246 [details, diff] relax ABI patch for gcc Upstream has added patches to wx/build.h as it was agreed that the GXX_ABI_VERSION that shipped with gcc 3.4 has been stable and does not affect wxWidgets. Discussion on this topic is at [1]. The patch includes commits [2] since d31cfba54091 excluding f1dfb27 which was for Visual Studio only. It should apply to all current and future versions until 3.1.2 where it already exists. Highly suggest changing the a subslot on this package as runtime breakage until rebuild of everything is complete or else mention a revdep-rebuild. This will prevent the existing ABI issues that plague wxGTK users and a small price to pay.

There are no subslots for wxGTK; so basically this revbump would then break all consumers yet again, this time without a GCC change?

Yes it will break for one, last time. Including the patch and revdep-rebuild instructions, when REPLACING_VERSIONS is non-empty, would be enough for this expected change. Users would no longer face each gcc version change to rebuild all wx apps/libs manually. This is the goal which makes the rebuild worth it.
I also have an issue regarding this. I must to run this command (thanks #gentoo) to solve it: emerge -1av wxGTK:3.0
See also Debian's patch at https://salsa.debian.org/freewx-team/wx/blob/wx3.0-debian/debian/patches/warn-for-compiler-abi-mismatch.patch Combining the two patches will likely enable a phase out as packages are recompiled. Debian's patch alone will cause warnings. Upstream's backported patch needs things recompiled if done alone.
(In reply to Brian Evans from comment #4) > Debian's patch alone will cause warnings. I don't think it'll cause any warnings. They had that initially, but it's commented out in current patch iteration (and I believe long before someone found the debian patch) due to causing issues if warning.
