There's your relocation of debug info.

It is entirely likely that the problem only happens because you're
using stabs.  It's supposed to work, but I've never tried it.  Try
taking a look at the contents of the .stab section at that offset
(0x32e4) in the file.  Then breakpoint after the call to
symfile_relocate_debug_section in elfstab_build_psymtabs, and see
what's at offset 0x32e4 now.  It should be a bit relocated.

In bfd_perform_relocation for the .stab section I see that at line 633 relocation is 0 for the static function horloge_read when it is 0x37a for the non static function HorlogeCheck. I guess that the .stab section is wrong for static function as seen in the readelf -r output. Only the non static have values != 0.

What do you recommend to use rather than stabs ?
