--- Comment #2 from Leandro Nini ---
Oh, now I see it, it wasn't that obvious in the first test. But why is the
compiler allowed to postpone the store after deleting the pointer? Is there
some undefined behavior involved here or what?

Getting a crash with snapshots gcc-9-20191221/gcc-8-20191220 and isl-0.22 on
x86_64-linux compiling the following reduced code using "-O2 -floop-block"
flags

--- Comment #13 from Leandro Nini ---
I've applied the patch to the 6.3.1 20170202 snapshot and the former test
compiles but this one triggers the same error:
typedef struct { float x1; } bx;
typedef struct {
int w;
short o;
} T2P;
T2P a;
i

Reduced testcase, ICEs with gcc -O2 -floop-interchange:
int a, b, d;
int **c;
int fn1() {
while (a)
if (d) {
int e = -d;
for (; b < e; b++)
c[b] = &a;
} else {
for (; b; b+
