Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: chengniansun at gmail dot com
GCC does not emit cast-align warning on the following code. Is this expected?
$: cat t.c
int *f(char * c, int n) {
return (int *)(c + 2);
}
$: clang-trunk -Wcast-align -c t.c
t.c:2:10: warning: cast from 'char *' to 'int *' increases required alignment
from 1 to 4 [-Wcast-align]
return (int *)(c + 2);
^~~~~~~~~~~~~~
1 warning generated.
