Bug ID: 89910
Summary: [7/8/9 Regression] ICE in make_ssa_name_fn, at
tree-ssanames.c:271
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Affects versions gcc-7 and higher at -O2+ :
$ cat z1.cc
int a, b;
void *f;
void g (int c)
{
b = ((int (*)[c][a]) f)[0][0][0];
}
void h (int d)
{
g (d);
}
$ g++-6 -c z1.cc -O2
$
$ g++-9-20190331 -c z1.cc -O2
