Bug ID: 90841
Summary: ICE in get_atomic_generic_size, at
c-family/c-common.c:6904
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Affects versions down to gcc-4.7 (gcc-4.6 gives an error) :
$ cat z1.c
int a[];
void f()
{ __atomic_load (&a, &a, __ATOMIC_SEQ_CST); }
$ cat z2.c
int a[];
void f()
{ __atomic_store (&a, &a, __ATOMIC_SEQ_CST); }
$ gcc-10-20190609 -c z1.c
z1.c: In function 'f':
z1.c:3:1: internal compiler error: Segmentation fault
