would be nice to avoid a lot of pain with debugging. Does it already exist?
WxGTK keeps a string WX_BUILD_OPTIONS_SIGNATURE currently saying "2.8 (no
debug,Unicode,compiler with C++ ABI 1002,wx containers,compatible with
2.4,compatible with 2.6)" and it is checked at runtime. C++ ABI is supposed
to be unchanged in Fedora 22. This string changed anyway because
__GXX_ABI_VERSION in gcc changed. Is this expected/correct? Each freshly
rebuilt wx application will crash now. After wxGTK is rebuilt, each old
application will crash. A provenpackager should probably step in.
That is a WxGTK bug. __GXX_ABI_VERSION can change, but usually the result
is still ABI compatible, g++ emits just some aliases when mangling has
changed.
