You brave soul for trying to compile with -fsee.
Nevertheless, yup, a bug.

Not a regression since -fsee is broken since ever and the sharing verifier is
new.

------- Comment #4 from pinskia at gcc dot gnu dot org 2007-12-09 21:54 -------
And here is a reduced testcase which can compiled with either the C or C++
front-ends:
int isLegalIdChar (char);
char get();
char z;
void FillBuffer ( void )
{
char c;
while(1)
{
c = get();
if (!isLegalIdChar(c))
break;
z = c;
}
}
