Summary sizeof(CSSRule) compile assertion failure
Jonathan Liu
Reported 2012-09-24 05:39:06 PDT
COMPILE_ASSERT(sizeof(CSSRule) == sizeof(SameSizeAsCSSRule), CSSRule_should_stay_small) fails when building with MinGW-w64 GCC 4.7.2. It previously compiled successfully with MinGW-w64 GCC 4.6.3. The problem seems to be a change in the default behavior when padding bitfields. MinGW GCC 4.7.x uses -mms-bitfields by default while MinGW GCC 4.6.x doesn't. Since the underlying type is unsigned, it pads to 32-bit when it should really be padding to 8-bit.
