Bug ID: 107777
Summary: [13 Regression] ICE in get_representative_path_var_1,
at analyzer/region-model.cc:4750
Product: gcc
Version: 13.0
Status: UNCONFIRMED

Severity: normal
Priority: P3
Component: analyzer

Target Milestone: ---
gcc 13.0.0 20221120 snapshot (g:a16a5460447eaaff0b4468064e4d7b1cc8fc42eb) ICEs
when compiling the following testcase w/ -fanalyzer:
int *
__errno_location (void);
long int
read (int, void *, unsigned long int);
struct IOBUF {
int fd;
};
void
do_getline_end_data (struct IOBUF *iop, int tree)
{
char end_data;
if (tree)
*__errno_location () = 0;
read (iop->fd, &end_data, sizeof end_data);
}
% gcc-13 -fanalyzer -c ofd9impz.c
during IPA pass: analyzer
ofd9impz.c: In function 'do_getline_end_data':
