Would you mind following https://wiki.gentoo.org/wiki/GCC_ICE_reporting_guide as much as you can, and we can help with any bits you get stuck on? Will do. Thanks. I've hit the same problem when building www-client/chromium-112.0.5615.121 with sys-devel/gcc-12.2.1_p20230304 and "-march=ivybridge". It did *not* happen with "-march=skylake". Adding "-fno-tree-vectorize" to CXXFLAGS made chromium build successfully for me. That's a bit strange since AFAIK tree vectorization should *not* be enabled by default at -O2 level, only -O3. The above is obviously just a workaround to make chromium build, GCC should not ICE even with all the optimization options turned on. (In reply to Maciej S. Szmigiero from comment #6) > That's a bit strange since AFAIK tree vectorization should *not* be enabled > by default at -O2 level, only -O3. GCC 12 introduces vectorisation at -O2 using -fvect-cost-model=very-cheap ('very-cheap' being a new level they introduced in the 12 release). Reproduced:
```

Reporting upstream.
The issue is fixed on my IvyBridge systems with the following upstream patch for sys-devel/gcc-12.2.1_p20230121-r1 https://gcc.gnu.org/git/?p=gcc.git;a=patch;h=cddfe6bc40b3dc0806e260bbfb4cac82d609a258 (In reply to David from comment #10) > The issue is fixed on my IvyBridge systems with the following upstream patch > for sys-devel/gcc-12.2.1_p20230121-r1 > > > https://gcc.gnu.org/git/?p=gcc.git;a=patch; > h=cddfe6bc40b3dc0806e260bbfb4cac82d609a258 Yeah, my intention is to chuck it in to today's 12 snapshot (which will be created tonight). It'll get backported upstream eventually too, probably/hopefully in time for 12.3.
