Segfault in w3c with PUT

Hello I'm runing the commandline tool from Libwww 5.1m
and testing HTTP PUT.  When ever the file I'm testing is
around or over 2MB, w3c segfaults...

>./w3c -put test_data -dest http://merced/destination
 EventOrder.. no event found for socket 4, type HTEvent_WRITE.
 WARNING: Fatal Error: Data transfer interrupted

 Segmentation fault

Is there a workaround or fix for this?

Here's a bit of debug information
