I've got a 100% repeatable crash (bus error) in
Curl_llist_insert_next().

I'm using curl 7.18.2, on Mac OS X 10.5.4:

Here's the backtrace:

(gdb) bt
#0 0x003080af in Curl_llist_insert_next ()
#1 0x003085f2 in Curl_hash_add ()
#2 0x002eb82f in Curl_cache_addr ()
#3 0x002ebade in Curl_resolv ()
#4 0x002fc5e1 in Curl_connect ()
#5 0x00306268 in Curl_perform ()
#6 0x0000484b in download_file (url=0x413080 "http://mapserver.flightgear.org/dlaction.psp?xmin=-120.937500&xmax=-118.125000&ymin=33.750000&ymax=36.562500&pgislayer=v0_irrcroppasturecover
", filename=0x17f656 "shape.tmp")

Here's the code:

        if( !(fp = openfile( filename, "wb" )) )
                return false;

        // set the url to download
        curl_easy_setopt( curl, CURLOPT_URL, url );

        // write to our file pointer
        curl_easy_setopt( curl, CURLOPT_WRITEDATA, fp );

        if( !curl_easy_perform( curl ) )

fp is valid, curl is valid and you can see that url is valid and the
value above.

I'm guessing it's not possible to determine a fix from the above. I
want to submit a quality bug report, so I've been trying to turn on
debugging for libcurl. I've tried using --enable-debug on configure
and CFLAGS=-g -O0 but I'm still not getting source in the debugger.

Any suggestions on additional flags that need to be enabled for
debugging or solutions to the crash?

Thanks,

Wade
