[OpenSER-Users] SIGILL when starting openser

[Christian Koch]

Hi Bogdan,

when logging to syslog these are the last lines I get:

    Apr 23 16:12:02 192 /usr/local/sbin/openser[12817]:
    DBG:core:init_mod: registering stats for usrloc
    Apr 23 16:12:02 192 /usr/local/sbin/openser[12817]:

    [/usr/local/lib/openser/modules/]

    DBG:core:find_cmd_export_t: found <load_sl>(0) in module sl
    [/usr/local/lib/openser/modules/]

All other messages I get are either DBG or INFO, no errors. But now I 
tried something different. I've set "fork=no", and now I'm getting a 
corefile. Backtrace of gdb is:

    (gdb) bt
    #0  0x0012ff8f in mod_init () at auth_mod.c:200
    #1  0x080ab61e in init_mod (m=0x8165048) at sr_module.c:461
    #2  0x080ab3f5 in init_mod (m=0x81650e8) at sr_module.c:456
    #3  0x080ab3f5 in init_mod (m=0x8165188) at sr_module.c:456
    #4  0x080ab3f5 in init_mod (m=0x8165228) at sr_module.c:456
    #5  0x080ab3f5 in init_mod (m=0x81652c8) at sr_module.c:456
    #6  0x080ab3f5 in init_mod (m=0x8165368) at sr_module.c:456
    #7  0x080ab3f5 in init_mod (m=0x8165408) at sr_module.c:456
    #8  0x080ab3f5 in init_mod (m=0x81654a8) at sr_module.c:456
    #9  0x080ab3f5 in init_mod (m=0x8165548) at sr_module.c:456
    #10 0x080ab3f5 in init_mod (m=0x8165618) at sr_module.c:456
    #11 0x080ab3f5 in init_mod (m=0x81656b8) at sr_module.c:456
    #12 0x080684a7 in main (argc=1, argv=0xbff668b4) at main.c:1355
    (gdb)

Looks like calling init_mod() recursively. I didn't study the openser 
code, but this backtrace looks strange to me.
If anybody is interested in the whole corefile, please mail me directly. 
I don't want to post such a large file to the list.

Thanks a lot for your help,
Christian
