Hi Daniel,
I was able to prevent the bus error by reverting part of commit
1b366aa1c6c37e2320da10fb68f0370199333f5d as below:
diff --git a/cfg/cfg_struct.c b/cfg/cfg_struct.c

+++ b/cfg/cfg_struct.c
@@ -295,8 +295,7 @@ static void cfg_destory_groups(unsigned char *block)

group->var_offset + mapping[i].offset);
+ memcpy(&old_string, block +
group->var_offset + mapping[i].offset, sizeof(char *));
if (old_string) shm_free(old_string);
}
I can’t really see why there would be a bus error… thoughts?
Thanks,
Spencer

Hi Daniel,
I haven’t yet but I will try to test shortly.
Here is the value of the block variable:
(gdb) p /s block
$1 = (unsigned char *) 0xffffffff76e5ded4 “"
Thanks,
Spencer

Hello,
hmm, they are multiple of 8, so they should be aligned to 64bits.
Or maybe the 'block' variable value is not aligned to 8bytes ...
Have you done any sip traffic via this kamailio instance. Is all ok at
runtime?
Cheers,
Daniel

Hi Daniel,
See below:
(gdb) p group->var_offset
$1 = 64
(gdb) p mapping[i].offset
$2 = 56
Thanks!

Hello,
can you get the values for group->var_offset and mapping[i].offset in
frame 0?

Hello,
I’m trying to get Kamailio running on Solaris 11 SPARC64 and I’m receiving a bus error on
shutdown. If needed, we can make SPARC hardware available for testing.
Thanks,
Spencer
