Bug ID: 105366
Summary: [11/12 Regression] ICE: in cmp_cst, at
analyzer/svalue.cc:309 with -O -fanalyzer
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: analyzer
Assignee: dmalcolm at gcc dot gnu.org
Reporter: zsojka at seznam dot cz
Target Milestone: ---
Host: x86_64-pc-linux-gnu
Created attachment 52859
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52859&action=edit
reduced testcase
The testcase got quite ugly while reducing (taking address of functions), but
it ICEs the same way as the original testcase; this might be different than
PR105365 , since this also fails in gcc-11
Compiler output:
$ x86_64-pc-linux-gnu-gcc -O -fanalyzer testcase.c
during IPA pass: analyzer
testcase.c: In function 'foo':
testcase.c:13:7: internal compiler error: in cmp_cst, at analyzer/svalue.cc:309

Thanks for filing this bug; I'm testing a fix.
Seems to be the same root cause as PR105365; I'm not sure why one manifests
with GCC 11 and the other doesn't.
