System: NetBSD sulley 3.0_STABLE NetBSD 3.0_STABLE (SULLEY) #2: Fri Feb 3 21:06:20 PST 2006
Architecture: i386
Machine: i386
>Description:
Building pkgsrc/devel/Coin on i386 with optimization enabled causes
an internal compiler error.  According to bulk build results, this
error also occurs on -current.
>How-To-Repeat:
The following is the minimal code to reproduce the error.

% cat > pr.cc <<EOF
class A {
public:
  void setOverride(const bool state);
  bool getState(const unsigned int bits);
};

inline bool A::getState(const unsigned int bits) {
  unsigned int flags = 0;
  return (flags & bits) != 0;
}

void A::setOverride(const bool state) {
  if (state != getState(0x80000000)) return;
}
EOF
% g++ -O -c pr.cc
pr.cc: In member function `void A::setOverride(bool)':
pr.cc:8: internal compiler error: in fold_single_bit_test, at fold-const.c:4653
