[Bug c++/27471] New: [4.2 Regression] ICE within build_c_cast cp/typeck.c:5434

[mueller at gcc dot gnu dot org]

Hi, 

due to the bitfield handling changes, C++ frontend now ICEs on this: 

=== Cut===
struct A { unsigned a:8; };

extern void b(unsigned char);

void breakme (A f)
{
  b((unsigned char) f.a);
}
=== Cut ===
bitfield-ice-1.cc: In function 'void breakme(A)':
bitfield-ice-1.cc:7: internal compiler error: in build_c_cast, at
cp/typeck.c:5434
Please submit a full bug report,
with preprocessed source if appropriate.
