Hi,
the following code doesn't compile. It's related to my PR 14203 (or from Debian
BR #233548). GCC 3.4.1 works fine.
André
struct Dummy
{
void foo();
};
const bool g_bAlways = false;
int main()
{
bool test;
if (g_bAlways)
{
if (Dummy* dummy = 0)
{
if (!test)
{
int d;
d = 1;
}
dummy->foo();
}
}
return 0;
}

Here's something shorter. It also crashes gcc 3.4.0 and 3.4.1.
=================================
void foo()
{
if (0)
if (int* p = 0)
int i=*p;
}

Roger, ii looks like your patch
http://gcc.gnu.org/ml/gcc-cvs/2003-04/msg00812.html
is responsible for the regression. Could you please have a look?

Indeed, this looks very similar to your shorter version in PR 14203.

Here's a testcase that looks even more like PR 14203
(and there's no dereferencing of the null pointer - even
if that was unreachable)
===============================
void foo()
{
if (false)
if (int i=0)
int j=i;
}
===============================
