--- Comment #5 from Martin Liška <marxin at gcc dot gnu.org> ---
Unfortunately the test ICE for couple of MPX test-cases compiled with LTO (I
wish we had MPX already removed). So:
$ gcc /home/marxin/Programming/gcc/gcc/testsuite/gcc.dg/lto/pr66221_*.c -flto
-mmpx -fcheck-pointer-bounds -O2
during IPA pass: comdats
lto1: internal compiler error: in ipa_comdats, at ipa-comdats.c:355
0x19c154c ipa_comdats
../../gcc/ipa-comdats.c:355
0x19c1744 execute
../../gcc/ipa-comdats.c:415
Problem is that one MPX clone is identified as nothrow, and then we do not
merge decls:
Merging nodes for test1.chkp. Candidates:

Not merging decls; DECL_ATTRIBUTES mismatch
And then we ICE in ipa-comdat. Ideas how to handle that? Should I somehow
ignore chkp clones in lto_symtab_merge_p?
