[Bug c++/37819] New: ice for legal code with no special flags

[dcb314 at hotmail dot com]

I just tried to compile the Suse Linux package kmymoney-0.8.9-23
with the new gcc version 4.4, snapshot dated 20081010.

The compiler said

kmymoneyaccountselector.cpp: In member function 'bool
kMyMoneyCheckListItem::isAlternate()':
kmymoneyaccountselector.cpp:149: internal compiler error: in cp_genericize_r,
at cp/cp-gimplify.c:823
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Preprocessed source code attached. No special flags required.

Reduced testcase:
struct kMyMoneyCheckListItem
{
   unsigned int m_known : 1;
 };
bool
isAlternate(kMyMoneyCheckListItem *a, kMyMoneyCheckListItem *above)
{
   a->m_known = above ? above->m_known : true;
}
