Would it be possible to send me preprocessed source ?
I do not have access to x86-64 box and ppc-linux box
in the lab has decided to not respond at the moment.
Well, the problem is that the same source works fine with stage1
compiler and crash in stage2, so what we are facing is an
misscompilation of gcc itself.
When -fdump-tree-ifcvt-stats is enabled, GCC emits
"Applying if-conversion" string in status file (.ifcvt).
It does not if-convert many loops, so it would be helpful
you can identify mis-compiled object file.
Meanwhile I'll try if I can reproduce it on powerpc-darwin.
I have started couple of bootstrap. Lets see. I'll be
offline couple for hours.
It however crashed for me on
i686-pc-linux box too.
