Extended Description

testcase:

struct X {
unsigned int e0 : 17;
unsigned int e1 : 17;
unsigned int e2 : 17;
unsigned int e3 : 17;
unsigned int e4 : 17;
unsigned int e5 : 17;
unsigned int e6 : 17;
unsigned int e7 : 17;
} attribute((packed)) x;

Compiling with the llvm-gcc C compiler:
gcc/llvm-types.cpp:1184: void StructTypeConversionInfo::addNewBitField(unsigned
int, unsigned int): Assertion `Size <= 64 && "Bitfield too large!"' failed.
packed17.c:10: internal compiler error: Aborted

Testcase reduced from Ada's s-pack17.
