Which version of the assembler are you using? I can't reproduce this
problem with current binutils. In fact, the symptoms look very
similar to those of the bug fixed with:
2000-09-01 Alexandre Oliva <aoliva@redhat.com>
* config/tc-sh.c (md_apply_fix): Map 32-bit relocations that
become PC-relative to BFD_RELOC_32_PCREL. Reject 16- or 8-bit
similar relocs.
Anyway, there is a bug, but it is in GCC. It isn't generating PIC
code for computed goto, which glibc's vfprintf uses.
Here's a patch that fixes this problem in GCC. Ok to install?
