seems to be an issue on 32-bit hosts: I get the same failure on
i686-pc-linux-gnu.

This is Solaris, so no glibc in sight ;-)
I'll send the Linux/i686 preprocessed source and uninit1 dump in private
mail. Reproduce with
ccplus -fpreprocessed go-diagnostics.ii -quiet -mtune=generic -march=pentiumpro
-O2 -Wextra -Wall -Werror -o go-diagnostics.s
