Camm,
Here is the gdb output for the MAC OSX plt issue.
I think the result is fairly definitive. See this section below:
Breakpoint 2, pltcomp (v1=0xbffaade0, v2=0x123ad4) at plt.c:25
25 const Plt *p1=v1,*p2=v2;
(gdb) n
27 return strcmp(stn(p1->n),stn(p2->n));
(gdb) p p2->n
$8 = 0x11574c "__srget"
(gdb) p p1->n
$9 = 0x5742d1 "___srget"
(gdb) n
29 }
(gdb) n
0x9000f8c8 in bsearch ()
(gdb) n
Single stepping until exit from function bsearch,
which has no line number information.
my_plt (s=0x5742d1 "___srget", v=0xbffff668) at plt.c:185
185 return -1;
(gdb) n
187 }
--------
It seems as if pltcomp is not respecting the leading underscore
for the comparison.
Can you suggest fix?
Regards,
Bill Page.
