Building www-client/firefox-72.0.1 with LTO enabled causes frequent crashes for me. Older versions and builds with LTO disabled work fine. Enabling/disabling graphics acceleration has no effect.

You might want to upgrade GCC to 9.2.0-r3 [1] which carries a fix which affects Firefox gcc lto builds or try a clang build. Afaik FF 72.0 still carries a patch to address the gcc issue, not sure about 72.0.1; but something might have changed nevertheless. [1] https://gitweb.gentoo.org/repo/gentoo.git/commit/sys-devel/gcc?id=649ef16ea81488d36fae3fa4a8881c9e665d2e7a

Same here for www-client/firefox-72.0.2[lto] with sys-devel/gcc-9.2.0-r3, on multiple machines. The issue is very easy to reproduce for me, I just need to start dragging any tabbed browsing tab button for FF to immediately crash with the backtrace similar to the one others here are getting. Re-emerging with USE="-lto" fixes things.
Do you think you could give directions on how to compile firefox with debug informations? The old standard of dropping an env file into /etc/portage/env/www-client/ with CFLAGS="${CFLAGS} -ggdb" CXXFLAGS="${CXXFLAGS} -ggdb" FEATURES="${FEATURES} splitdebug" didn't work for me.
Created attachment 610020 [details] segfault of firefox-72.0.2[lto] with gcc-9.2.0-r3 this backtrace is from randomly surfing around, opening and closing tabs. the easiest way to reproduce is: have two tabs open, and try to reoder or rearrange them using the mouse. upstreams binary from www-client/firefox-bin isn't affected, they use CC=clang
www-client/firefox-73.0 is affected, too.
I wasn't even able to build 73.0 with USE=lto.
(In reply to Tomasz Golinski from comment #7) > I wasn't even able to build 73.0 with USE=lto. Feel free to test updated ebuild in mozilla overlay and report your findings. We will move to tree within 48 hours.
the sefaults are gone now with the updated patch. tested on amd64 and arm.
I also confirm the version from mozilla overlay builds fine and doesn't seem to crash either. I also updated nss to the overlay version.
I spoke too early. I tried dragging the link to bookmark toolbar and Firefox crashed immediately.

Yes, www-client/firefox-73.0[lto] now builds fine, however still often crashes at runtime due to this bug.

When someone wants to debug it feel free to debug and provide a patch. I do not build with lto or pgo on musl. Whissi was the one who introduced the code and wanted to support it so that is the developer you will need to contact if you need assistance.

Without lto and pgo crashes at runtime too
(In reply to Ilya Gorskin from comment #15) With same backtrace in mozilla::gfx::InlineTranslator? When browsing or when reordering tabs?
(In reply to Ilya Gorskin from comment #15) > Without lto and pgo crashes at runtime too The non-lto, non-pgo build doesn't crash for me at all.
I don't know if it helps much but I'm seeing the same crash in the same location. In my case, all I have to do is mouse over a particular link on a particular page. Presumably it will go away when I recompile without -lto which I will do now.

I suppose I should add that it's actually www-client/firefox-73.0.1 crashing on my in the same location compiled with lto.
I've found firefox-74.0-r1[lto] crashing on packages.gentoo.org, while non-lto build works fine.
FYI: www-client/firefox-75.0-r1[lto] built with GCC 9.3.0 works fine for me on multiple machines.
