Bug ID: 101143
Summary: [12 Regression] ICE: incompatible types: 'unsigned
int' and 'long unsigned int'
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: ice-on-invalid-code
Severity: normal
Priority: P3
Component: analyzer
Assignee: dmalcolm at gcc dot gnu.org
Reporter: asolokha at gmx dot com
Target Milestone: ---
gcc-12.0.0-alpha20210620 snapshot (g:69d80f0f2f0bb8a88cd82d8ab6c4b92cf8013ca1)
ICEs when compiling the following testcase w/ -fanalyzer:
void *
malloc (unsigned int);
void *
foo (void)
{
return malloc (sizeof (int));
}
% aarch64-linux-gnu-gcc-12.0.0 -fanalyzer -w -c pf0wnfaz.c
during IPA pass: analyzer
pf0wnfaz.c: In function 'foo':
pf0wnfaz.c:7:10: internal compiler error: incompatible types: 'unsigned int'
and 'long unsigned int'
7 | return malloc (sizeof (int));
