The invalid code below results in "internal compiler error: Segmentation fault"
with a checking version of GCC 4.0.1. Does not happen with GCC 3.3.4 or Apple GCC 4.0.0.
Like the code for bug 22603, this is a greatly-reduced and anonymized excerpt, found by Daniel
Wilkerson's Delta, from a real PalmSource file. (This reduction was found by looking for a segfault; the
previous reduction looked for any compiler error.)
I don't think this is the same bug as my 22508, since that one also happened with Apple GCC 4.0.0.
It doesn't sound to me like 21975 or 22441 either.
class NameOne;
class NameTwo : virtual public SAtom
{
virtual NameOne* NameThree();
};
class NameFour : virtual public NameFive
{
class NameOne : public NameTwo
{
virtual NameOne* NameThree();

Like bug 22603, this is tracked by PalmSouce bug 104911, though I suspect it's different.

Here's an example that only contains one error:
==============================================
struct A;
struct B
{
virtual A* foo();
};
namespace N
{
struct A : B
{
virtual A* foo(); // should be ::A*
};
}

Here's another segfault, originally PalmSource bug 105158, but after Delta reduction it looked similar:
class nameOne : public nameTwo, public nameThree, public nameFour, public nameFive, public nameSix
{
void nameSeven(const nameEight &name, const nameNine & icon);
virtual void nameSeven(const nameEight& name, const nameTen &icon);

That is a different issue, please file as a seperate bug.

The patch looks good. A checking=yes build, with patches 20161-8277, 22508-2005-08-00326,
22600-9330, and 22604-2005-08-00334, rejected the file BBinder_segfault.ii without an ICE. (A
checking=all build is still building.) A run of 'make check' didn't report any unexpected errors.
