Bug ID: 102463
Summary: ice in fold_using_range::relation_fold_and_or
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
For this C code:
_bfd_elf_merge_symbol_h, _bfd_elf_merge_symbol_h_1;
_Bool _bfd_elf_merge_symbol_olddef;
_bfd_elf_merge_symbol() {
_Bool newdef = bfd_is_com_section(), ntdef, tdef;
_bfd_elf_merge_symbol_olddef = _bfd_elf_merge_symbol_h;
if (_bfd_elf_merge_symbol_h_1) {
ntdef = newdef;
tdef = _bfd_elf_merge_symbol_h;
} else {
ntdef = _bfd_elf_merge_symbol_h;
tdef = newdef;
}
if (tdef && ntdef)
;
}
compiled by recent gcc and flag -O2, does this:
during GIMPLE pass: evrp
elflink.c: In function ‘_bfd_elf_merge_symbol’:
elflink.c:15198:1: internal compiler error: Segmentation fault
0xd6a899 crash_signal(int)
../../trunk.git/gcc/toplev.c:328
0x1a73c3c fold_using_range::relation_fold_and_or(irange&, gimple*, fur_source&)
../../trunk.git/gcc/gimple-range-fold.cc:1365
The problem first seems to occur sometime between git hash
947332a4e22aef9b, from last week, and hash 83aac698835edcdb
from yesterday.
