Created attachment 805150 [details] mingw64-toolchain-10.0.0_p1:20220914-161231.log.xz build log
Seems caused by one of the -fstack flags, surprised it's not getting stripped by strip-unsupported-flags. I'll look into this, but for now it should build if you remove them. Trying same flags I got this in the config.log: <snip>: undefined reference to `__stack_chk_fail' collect2: error: ld returned 1 exit status
Hm, it can build mingw crt with it (so not auto-stripped) but then everything fails regardless of the flags because crt now always needs ssp symbols (which is not re-implemented by mingw). Tried to use gcc's libssp in stage2 but then stage3's libstdc++ breaks instead. Think I'll just filter -fstack-protector* when cross-compiling (will still be used for the compiler itself), or at least for now.

Will try to get libssp to work, better reverted+failing for now given this can create a unusable build if used ssp. Could filter further to include gcc but will also need to filter on about every mingw packages. For those just wanting this to work meanwhile, just don't enable ssp on neither this nor wine.

It doesn't help that libssp is notoriously brittle. When we were discussing if we should use it for musl ages ago, the response from the musl community was emphatically "please don't". Its effectiveness is doubtful as well. Also, of course, note that if using GCC as system compiler, no need to explicitly set -fstack-protector-strong anyway (it's default). -fstack-check is something different and also considered obsolete. -fstack-clash-protection is its replacement (which hardened profiles set at least, not normal yet IIRC).
Yeah, more I look I this I think I may just slap filter for every mingw ebuilds.
Created attachment 805201 [details] config.log I can confirm the __stack_chk_fail error in config.log. Also removing the -fstack-protector-strong and -fstack-check builds the package.

This turned out to be fine, was misled that it may have leaked to gcc's own libraries rather than just mingw's crt. Still require filtering ssp on every mingw packages though, strip-unsupported-flags can't pickup that this will fail with a basic `int main(void) { return 0; }` compiler test.

Thanks for this info Sam. The info pages for gcc-12 has no info regarding -fstack-check being obsolete. It even says, that -fstack-clash-protection may provide limited protection for static stack allocation if the target supports -fstack-check=specific. If I read this correct, -fstack-clash-protection might even use -fstack-check=specific internally.

Bootstrapping using USE=ssp seems to work both with and without libssp. The libscrypt reproducer from the patch's old link also builds fine with this version.

There may be real issues in dxvk & others, but support for this is new in mingw (also only partial), and believe using this can be considered too experimental/early "here". Still allowing it with USE=custom-cflags for those that really want it and don't mind if it breaks some components they don't use. Skipping revbump given it's an unusual configuration given users normally don't pass this in *FLAGS but rather rely on the toolchain's defaults. mingw64-toolchain-11.0.1 will also be keyworded in not that long for rebuilds. Only needed for mingw runtime, so the toolchain itself is still using it through the system-wide defaults. May revisit eventually. Not doing this for crossdev+mingw64-runtime main package again, these are for more expert use in the first place.
