Comment(by wgmitchener):
Doing some work with gdb with ghc-bug-003 (which I'll attach in a minute)
On Ubuntu 12.10 with GHC 7.4.2 (no SELinux, no seg fault), the call to
set_callback comes out like this:
{{{
Breakpoint 1, set_callback (f=0xb7b3f02c, d=10, fin=0xb7b3f00c) at
Callback.c:18
18 p_callback = f;
(gdb) x/i f
0xb7b3f02c:call 0x80a1358 <adjustorCode>
(gdb) print adjustorCode
$1 = {<text variable, no debug info>} 0x80a1358 <adjustorCode>
}}}
On Fedora 17 with GHC 7.4.2 (with SELinux, seg faults), the call to
set_callback comes out like this:
{{{
Breakpoint 1, set_callback (f=0xb7ffd02c, d=10, fin=0xb7ffd00c) at
Callback.c:18
18 p_callback = f;
(gdb) x/i f
0xb7ffd02c: call 0x82274b8
(gdb) print adjustorCode
$1 = {<text variable, no debug info>} 0x82264b8 <adjustorCode>
}}}
so is something going wrong with this adjustorCode function?
