The session below, with the file below, gives "internal compiler error: in int_mode_for_mode, at stor-
layout.c:251". The error only occurs at -O1 or higher. This sounds like bug 17407, but that's
supposedly fixed and didn't require optimization. The file is an odd-looking Delta reduction of a much
larger file, which was originally supposed to be valid code; but I haven't gotten the include paths set up
properly yet.
File:
{
};
class NameOne;
{
{
{
{
{
}
{
}
}
}
}
}
struct NameTwo::private_data {
struct offsets {
};
};
class NameThree : public NameFour {
NameThree( NameOne frame,
const char *name,
NameFive *target,
float min,
float max,
orientation direction);
};
NameThree::NameThree(NameOne frame, const char *name, NameFive *target, float minv, float maxv,
orientation direction)
: NameFour(frame, name, target, minv, maxv, direction)
