  I thought I'd provided that information already. Should I attach the
  preprocessed .s file?
Sorry, I didn't see that before.  It is he first LEA that crashes.

Let's blindly test if moving the float constant into data space helps:

  This is a static-only build, as the later GCC build will be built with a
  static libgcc. (I'm also using --with-pic, but the same failures result
  without that.)
I am not sure --with-pic has any effect.

  Interestingly, a shared-only build passes all tests.

Curious.  If one build type causes trouble, it is usually the shared
  I just see an invocation of plain "as" in there. If the problem is
  down to the linker, however, this would be the only instance of it
  that I'm aware of.
WHich as version is this?  What does "which as" print?
What does "as --version" or somesuch option print?

  Surely this is something simple enough! Would you want to see assembly
  from one of the generic .c files?
If the above patch fails, I'll send some C snippets for compilation...
