The following invalid code snippet causes an ICE on mainline:
============================================
struct A
{
double d : 2;
A() {}
};
============================================
bug.cc:3: error: bit-field 'double A::d' with non-integral type
bug.cc: In constructor 'A::A()':
bug.cc:4: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in perform_member_init, at cp/init.c:350
Please submit a full bug report, [etc.]
Replacing the constructor by a destructor I get:
============================================
struct A
{
double d : 2;
~A() {}
};
============================================
bug.cc:3: error: bit-field 'double A::d' with non-integral type
bug.cc: In destructor 'A::~A()':
bug.cc:4: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in push_base_cleanups, at cp/init.c:2903
Please submit a full bug report, [etc.]
This is a very recent regression (GCC 4.2.0 20060527 was not affected).
