Package: gcc-11 Version: 11.3.0-5 Severity: important Tags: upstream X-Debbugs-Cc: ma.uec...@gmail.com
When investigating why BART fails to build with LTO because GCC crashed, I reduced this to the following test case. Upstream bug report: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106702 $ cat test.c extern void bar(int M, int N, float S[(N > M) ? M : N]); void foo(int M, int N) { bar(M, N, 0); } $ gcc-11 -I ../src/ -flto test.c during IPA pass: modref test.c:8:1: internal compiler error: tree code ‘c_maybe_const_expr’ is not supported in LTO streams 8 | } | ^ 0x7fa316e01209 __libc_start_call_main ../sysdeps/nptl/libc_start_call_main.h:58 0x7fa316e012bb __libc_start_main_impl ../csu/libc-start.c:389 Please submit a full bug report, with preprocessed source if appropriate.
