[Bug c/41476] New: [4.5 regression] __typeof__ expands to const type

Sat, 26 Sep 2009 10:09:31 -0700 

When __typeof__ is applied to a conditional expression that contains a call to
a const function it expands to a const type.

$ cat tgmath.c
int foo (int) __attribute__ ((const));

void
test (void)
{
  __typeof__ (1 ? foo (0) : 0) texpr;
  texpr = 0;
}
$ gcc -c tgmath.c 
tgmath.c: In function ‘test’:
tgmath.c:7:3: error: assignment of read-only variable ‘texpr’
