It would be nice if could provide a manageable reproducer. Did you try delta
already?

Thanks in advance.

Nope, I did not. Will take a look.

Also you might want to try 4.4.2 which has fixed some TOC related ICEs.

Unfortunately, I am stuck with this version but I will try that to find out if
it does fix the issue to make a case for upgrading.
It seems to be related to the use of long double. Does that make any sense?

Do you know how long it is expected to take? It's been running since you
suggested it. I just want to know if it is guaranteed to finish at some point.

Ok, I ran the delta program for a few days and got this message:
Died at /home/s.somani/thirdparty/delta-2006.08.03/delta line 123, <> line
64641
Doh!
I'll try and see if I can get another test case.

Aha, found a small test case:
int main()
{
long double d;
bool b = static_cast<long double>(0) == d;
}

I've narrowed it down to this invocation:
g++ -o octonion_test.o -c -mxl-compat ld_break.cpp
So it's caused by some interaction with -mxl-compat
