Hello Bogdan.

Today I recompiled OpenSIPS by enforcing 64bits compilation (gcc -m64
flag), and OpenSIPS run without problems.

I think you are right, and the problem is related to variables alignment,
but, I am not sure why.

Regards.

Hello Bogdan.

Previously we have not had problems using OpenSIPS compiled for 32bits on
Sparc. I am not using any particular option; Makefile is performing the
guessing itself.

I will try to compile and test on 64 bits.

Thanks and regards.

Message:
It seams it is a issue with the arch detection - I guess "sparc" is 64b
arch and when opensips compiles as for 32b, some mem alignment is screwed.


Do you use any particular compile options or you let the Makefile to do
all the detection ?

Regards,
Bogdan

Hello Bogdan

I am running on SPARC, but OpenSIPS is compiled with 32 bits default
compilation.

(gdb) p ujiffies
$1 = (utime_t *) 0xfcc040ec
(gdb) x 0xfcc040ec
0xfcc040ec:     0x00000000
(gdb) x ujiffies
0xfcc040ec:     0x00000000
(gdb) x *ujiffies
0x0:    Cannot access memory at address 0x0
(gdb) p *ujiffies
$2 = 0

Please print "jiffies" also,

Another question - are you running on a 32 or 64 arch ?

Thanks and regards,
Bogdan
