Re: [sr-dev] Problem load db_perlvdb.so module

Hi, Seems there are some serious problems with db_perlvdb. It gives segmentation fault as soon as i set it as db url for any module e.g. acc, sip_trace, msilo and so on. Here is back-trace of core dump, -- #0  0xb57653dd in parseurl (url=0xaf41ba5c "\340\352\245\266\062") at perlvdbfunc.c:60         cn = 0x1 <Address 0x1 out of bounds> #1  0xb5765af6 in perlvdb_db_init (url=0xaf41ba5c "\340\352\245\266\062") at perlvdbfunc.c:123         res = 0x5         cn = 0xaf539cdb "\270"         obj = 0x0         consize = 32         __FUNCTION__ = "perlvdb_db_init" #2  0xaf3f81c2 in mod_init () at msilo.c:335         avp_spec = {type = PVT_AVP, getf = 0xb5f86c50 <pv_get_avp>, setf = 0xb5f8a8a2 <pv_set_avp>, pvp = {pvn = {type = 0, nfree = 0, u = {                 isname = {type = 1, name = {n = -1230637607, s = {s = 0xb6a5f5d9 "msilo_extra_hdrs)", len = 16}, re = 0xb6a5f5d9}},                  dname = 0x1}}, pvi = {type = 0, u = {ival = 0, dval = 0x0}}}, trans = 0x0}         __FUNCTION__ = "mod_init" #3  0x081e6b7c in init_mod (m=0xb6a4d9b0) at core/sr_module.c:972         __FUNCTION__ = "init_mod" #4  0x081e6e82 in init_modules () at core/sr_module.c:1001         t = 0x544c1e2c         i = -1         __FUNCTION__ = "init_modules" -- Thank you.

Then i looked through the source code but no success. After some googling, i found following link which states that perl.so was remained to app_perl.so since v4.x.
