Hello,
if I build pjproject-2.3 this way:
$ ./configure
$ make dep
$ make clean
$ make
when parsing an erroneous message i.e in From header using
pjsip_parse_msg function I get NULL as result, and some points in error
list.
if I build the pjproject-2.3 this other way
$ CFLAGS=-g ./configure
$ make dep
$ make clean
$ make
when parsing same error message with wrong From header it returns a non
NULL result, with everything OK but From header, and an error list with
clues.
I assume this second behavior is the correct one.
Trying to debug this, in sip_parser.c in function:
static pjsip_msg *int_parse_msg( pjsip_parse_ctx *ctx,
pjsip_parser_err_report *err_list)
I find the problem occurs after an exception variable pj_bool_t
parsing_headers; does not return the right value.
It seems to me when optimization parsing_headers variable is stored in a
register and then not recovered right after longjmp.
Then I have tried to set this variable as "volatile" but then I get
segfaults.
Can anyone solve this bug, or point me with some clues?
Thanks,
Vicente.
