Comment(by PHO):
I have examined the problem a bit:
Linker.c:4265:
{{{
#ifdef powerpc_HOST_ARCH
else if(scat->r_type == PPC_RELOC_SECTDIFF
|| scat->r_type == PPC_RELOC_LO16_SECTDIFF
|| scat->r_type == PPC_RELOC_HI16_SECTDIFF
|| scat->r_type == PPC_RELOC_HA16_SECTDIFF
|| scat->r_type == PPC_RELOC_LOCAL_SECTDIFF)
#else
else if(scat->r_type == GENERIC_RELOC_SECTDIFF
|| scat->r_type == GENERIC_RELOC_LOCAL_SECTDIFF)
#endif
{
struct scattered_relocation_info *pair =
(struct scattered_relocation_info*)
&relocs[i+1];
if(!pair->r_scattered || pair->r_type !=
GENERIC_RELOC_PAIR)
barf("Invalid Mach-O file: "
"RELOC_*_SECTDIFF not followed by
RELOC_PAIR");
word = (unsigned long)
(relocateAddress(oc, nSections, sections,
scat->r_value)
- relocateAddress(oc, nSections, sections,
pair->r_value));
i++;
}
}}}
The relocation problem occured at the following line:
{{{
- relocateAddress(oc, nSections, sections,
pair->r_value));
}}}
Investigating further with gdb:
{{{
(gdb) p *scat
$11 = {
r_scattered = 1,
r_pcrel = 0,
r_length = 2,
r_type = 8, // PPC_RELOC_SECTDIFF
r_address = 2237192, // 0x00222308
r_value = 3585652
}
(gdb) p *pair
$13 = {
r_scattered = 1,
r_pcrel = 0,
r_length = 2,
r_type = 1,
r_address = 0,
r_value = -60264 // wtf?
}
(gdb) p (unsigned long)pair->r_value
$43 = 4294907032 // 0xffff1498: Way too large.
}}}
