CONFIG_DEBUG_INFO=y is why I never hit it before.
It does not seem to be just one dodgy Redhat compiler (as I assumed in
the Bugzilla entry) but the whole 3.4 series of gcc which makes our
resolution of saying that this specific compiler is broken invalid.
Considering that we officially support all compilers >= 3.2 this is just
one more case where we have to add to the kernel a workaround for a
broken compiler.
Yes. I'm happy to write off a specific rpm package, but a whole series
is a different matter.
Adding
if (PREALLOCATED_PMDS == 0)
return;
in the appropriate places with a small comment seems like the right answer.
