Bug ID: 65054
Summary: internal compiler error: in maybe_constant_value, at
cp/constexpr.c:3646
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: regression
Assignee: unassigned at gcc dot gnu.org
Reporter: holger.hopp at sap dot com
following code throws an internal compiler error with g++-5.0 (gcc-5.0 works):
typedef char * CP;
const char * foo (void)
{
return ((const CP)"abc"+1);
}
$ g++ -c tst.c
tst.c: In function ‘const char* foo()’:
tst.c:5:28: internal compiler error: in maybe_constant_value, at
cp/constexpr.c:3646
return ((const CP)"abc"+1);
