Here's a reduced testcase that uses all RAM:
=============================
template<int> void foo()
{
throw A;
}
struct A
{
virtual ~A();
};
void bar()
{
foo<0>();
}
=============================
Commenting out the virtual destructor gives the ICE in c_expand_expr.
I don't think we can rate this as a regression:
All released version from 2.95.3 till 3.3.5 ICE on that code.
The couple of snapshots from Phil's regression hunter that do
not ICE issue a very strange error message:
input.cc: In function `void foo() [with int = 0]':
input.cc:12: instantiated from here
input.cc:3: non-lvalue in unary `&'
To me that looks like garbage found in memery. A more elaborate example
can probably turn this into an ICE.
So closing as fixed in gcc 3.4.0.
