Bug ID: 107826
Summary: ice during GIMPLE pass: slp
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
For the following reduced C code, compiled as follows:
$ ~/gcc/results/bin/gcc -c -O2 -std=c99 bug864B.c
during GIMPLE pass: slp
bug864B.c:3:1: internal compiler error: Segmentation fault

C code is:
enum { CPL_TYPE_FLOAT, CPL_TYPE_FLOAT_COMPLEX } __assert_fail;
cpl_image_multiply_scalar_nxy;
cpl_image_multiply_scalar_self() {
switch (cpl_image_get_type()) {
double *pio;
unsigned long i;
pio[i] *= 0;
case CPL_TYPE_FLOAT:
for (; cpl_image_multiply_scalar_nxy; i++)
pio[i] *= 0;
for (; cpl_image_multiply_scalar_nxy;)
case CPL_TYPE_FLOAT_COMPLEX: {
_Complex *pio = cpl_image_multiply_scalar_self;
_Complex cscalar = __assert_fail;
for (;; i++)
pio[i] *= cscalar;
}
}
}
The code seems to first go wrong sometime between git hash 2b2f2ee49a33419f
and 59cc4da605e5cb8e, a day later.
