Almost definetly not your fault

Thanks for your bug report. I believe your problem is twofold:

a) The function you are seeing is private to glibc 2.1.1:
0001defc t __setfpucw

   This is indicate by the lower case 't' here; an external symbol
   would have a 'T'. You don't explain who provides
   trapfpe.c. Whatever this is, it is using some function that it was
   not supposed to use.

b) You are reporting this to bug-gcc, which is the address for bugs in
   the GNU Compiler Collection. This seems to be more a problem with
   the C library; please use the "glibcbug" script to report such a
   bug (to a different address).

Kind regards,
Martin
