The following valid code snippet triggers an ICE since GCC 3.4.0:
==========================
struct A
{
int i;
};
template<int> void foo()
{
int x[A().i];
}
==========================
bug.cc: In function 'void foo()':
bug.cc:8: internal compiler error: in value_dependent_expression_p, at
cp/pt.c:12761
Please submit a full bug report, [etc.]
The following similar code snippet triggers an ICE since GCC 4.0.0:
==========================
struct A
{
static int i;
};
template<int> void foo()
{
int x[A::i];
}
==========================
bug.cc: In function 'void foo()':
bug.cc:8: internal compiler error: tree check: did not expect class 'type',
have 'type' (record_type) in contains_placeholder_p, at tree.c:2190
