out as completely empty files (or in one case as a precisely 64K sized file
that gives a "File format not recognized" error"), and the latest 2.6.31-rc
git can't be built at all.
Hmm. This sounds more like the binutils bug that people had. Sounds like
an assembler bug if the *.o file ends up being empty or at some fixed
size. If it was cc1 that fails, I'd expect to not see an *.o file at all,
since it didn't generate good assembly.
In fact, your behavior sounds like the thing that produces the *.o files
core-dumped or died for other reasons, and had a 64kB buffer that either
got flushed or not. That would explain the "zero or exactly 64kB" size.
It could be ccache too, of course.
