""" Please submit a full bug report, with preprocessed source if appropriate. """ https://wiki.gentoo.org/wiki/Gcc-ICE-reporting-guide has a few hints on how to extract selfcontained example.
Tried to reproduce it on vanilla ~x86 chroot to match *FLAGS and USE flags and did not succeed. We'll need a preprocessed example. Reproducer likely heavily depends on headers of some dependencies (jpeg, qt, etc.) as gcc fails assertion on inlining decision.
