This one is hardly an annoying bug. You need
a) nested functions,
b) using floating point,
c) with an unusual set of callee saved fprs,
d) and -Os.

Ah, the #c3 fail on powerpc was due to a powerpc glibc pthread_once bug. And
comment #36 should have read:

On thinking about this a little more, the idea of using /proc/self/auxv isn't
that good. MD_FALLBACK_FRAME_STATE_FOR is only needed for older kernels

I believe this is triggered by powerpc turning on -fsection-anchors by default,
and a section anchor bug loses the alignment. The classes are all nicely

So the section anchor code places vars (and constants) in blocks according to
their alignment and sizes (varasm.c:place_block_symbol). The calculations

No, of course that doesn't work. We make references into the section anchor
