[OpenSIPS-Users] segmentation fault when calling pkg_malloc

[Chevio]

Hi, All,

I am getting a segmentation fault when calling pkg_malloc from a custom
module in opensips 1.4.4 notls,

here is the offending code :

int tncgw_ip_lookup(struct sip_msg* msg, char* _para1, char* _para2)
{

	str  _user_ip;
	db_res_t* db_res = NULL;
	char* strsql=NULL;
	char* to_prefix=NULL;
	char* new_uri=NULL;
	char* new_to=NULL;
	str strsqlstr;
	str techprefix;
	str to;
	int retval=-1;
	int dbg=1;

	if(dbg)LM_INFO("TNCGW ip_address_lookup 2009.03.11.a beta\n");

	techprefix.s=NULL;
	_user_ip.s=NULL;

	if(dbg) LM_INFO("---Memory allocation\n");

	strsql=pkg_malloc(100);
	new_to=pkg_malloc(MAX_URI_SIZE); ## this is the line 97
	new_uri=pkg_malloc(MAX_URI_SIZE);
	to_prefix=pkg_malloc(8);


and here is the  back trace

does it mean I ran out of memory? if that is the case pkg_malloc should
return a 0 instead of crashing.

I will appreciate any help.
