>Environment:
Tested with 3.2.2, 3.3 and 3.4 on sparc-sun-solaris and with very recent
3.4 on x86-linux.
>Description:
The following code snippet ICEs with 3.2.2, 3.3 and 3.4, 3.2-release
issued an error, i.e. this is a regression. Compile with -std=c99!
void f ()
{
for (; int ; );
}
The ICE doesn't happen in c89 mode and is probably related to
c99 blocks because this produces the same ICE:
void foo ()
{
while (int i);
}
ehrhardt@huon:~ > ~/gcc/install/bin/gcc -std=c99 var2.c
var2.c: In function `foo':
var2.c:3: error: parse error before "int"
var2.c:4: internal compiler error: in genrtl_compound_stmt, at c-semantics.c:726
