I'm running the latest beta release (with ./configure
--enable-debug)

Enclosed are:

1. stack trace
2. offending piece of C++ that causes the problem and
local vars (can not provide more source as I am
modifying someone else's)

Program received signal SIGSEGV, Segmentation fault.
0x402a8321 in strncasecmp () from /lib/libc.so.6
(gdb) bt

============================

(gdb) frame 6

394 while( ( mstate = curl_multi_perform(
hmulti, &num ) ) != CURLM_CALL_MULTI_PERFORM && num !=
0 );

(gdb) info locals
num = 5
ret = true
msg = (CURLMsg *) 0x8063278

(gdb) frame 5
#5 0x4003c46c in curl_multi_perform () from
/usr/lib/libcurl.so.2
(gdb) info locals
No symbol table info available.

What do I need to enable in curl to be able to view
the locals ?

Thanks
