Bug ID: 102563
Summary: ice during GIMPLE pass: vrp-thread
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 source code:
int _bdf_parse_glyphs_bp;
long _bdf_parse_glyphs_nibbles;
void _bdf_parse_glyphs_p()
{
long p_2;
_bdf_parse_glyphs_nibbles = p_2 << 1;
for (; 0 < _bdf_parse_glyphs_nibbles;)
if (1 < _bdf_parse_glyphs_nibbles)
_bdf_parse_glyphs_bp = _bdf_parse_glyphs_p;
}
compiled by recent gcc trunk and compiler flag -O2, does this:
$ /home/dcb/gcc/results/bin/gcc -c -O2 bug762.c
bug762.c: In function ‘_bdf_parse_glyphs_p’:
bug762.c:12:28: warning: assignment to ‘int’ from ‘void (*)()’ makes integer
from pointer without a cast [-Wint-conversion]
12 | _bdf_parse_glyphs_bp = _bdf_parse_glyphs_p;
| ^
during GIMPLE pass: vrp-thread
bug762.c:4:6: internal compiler error: in upper_bound, at value-range.h:531
4 | void _bdf_parse_glyphs_p()
| ^~~~~~~~~~~~~~~~~~~
0x1b7a732 irange::upper_bound() const

The bug first seems to occur sometime between git hash
