Created attachment 923317 [details] Full Build Log Hi, this is my first bug report, I'm filling it out following recommendations from the Wiki (that I can't post a link to due to my account being brand new), if there's anything missing, let me know. --- Steps to reproduce: 1. Enable LTO via make.conf: WARNING_FLAGS="-Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing" COMMON_FLAGS="-O2 -pipe -fomit-frame-pointer -fno-semantic-interposition -ftree-vectorize -fvect-cost-model=dynamic -flto=auto -floop-block -fgraphite-identity -floop-parallelize-all ${WARNING_FLAGS}" LDFLAGS="${LDFLAGS} ${WARNING_FLAGS}" 2. Build x11-libs/wxGTK emerge -va x11-libs/wxGTK-3.2.6 3.

I have -fno-semantic-interposition set in make.conf. The build succeeds when disabling LTO for this package following the Wiki's recommended workaround of creating an env drop-in file and using it for this package: --- Contents of /etc/portage/env/nolto.conf # Env setup to disable LTO and related warnings for problematic builds DISABLE_LTO="-Wno-error=odr -Wno-error=lto-type-mismatch -Wno-error=strict-aliasing -fno-lto" CFLAGS="${CFLAGS} ${DISABLE_LTO}" CXXFLAGS="${CXXFLAGS} ${DISABLE_LTO}" FCFLAGS="${FCFLAGS} ${DISABLE_LTO}" FFLAGS="${FFLAGS} ${DISABLE_LTO}" --- Contents of /etc/portage/package.env/nolto x11-libs/wxGTK nolto.conf
Right. What I mean is, this failure may require LTO *and* -fno-semantic-interposition (seen it before with the strange 'note: ought to match virtual method ‘__cxa_pure_virtual’ but does not' bits).

Oh, got you. I'll try without that flag, but with LTO enabled, and report back.

You were correct, compilation finishes successfully when forcing that flag back on by passing -fsemantic-interposition. I'll update the bug report's title.
