package:
binutils-2.9.1
compiled using:
egcs 1.03, libc.so.6 on Red Hat 5.2 Linux
host system:
i586-pc-linux-gnu
target system:
h8300-hitachi-hms
problem:
linker h8300-hitachi-hms-ld core dumps when
attempting to link with any archive file.
investigated core file with gdb:
program core dumps after executing line 1252
in file binutils-2.9.1/bfd/coff-h8300.c
function "h8300_bfd_link_add_symbols" in file coff-h8300.c is broken:
//

//
> 1228 unsigned long reloc_size, reloc_count, i;
> 1229 asymbol **symbols;
> 1230 arelent **relocs;

//
// bfd_get_reloc_upper_bound returns -1 because

I changed line 1234 to read:
1234 if ((long)reloc_size <= 0L)
this stops the core dumps, but the linker still doesn't handle
archives correctly. The map file shows the archives being loaded
but there are no symbols showing up from the archives.
