Last user: [<c016b21b>](expand_files+0x104/0x2e8) Anyone seen this? It only happens with gpilot apparently, but not with pilot-link. The gpilot somehow makes the Treo 650 to disconnect, and that apparently triggers a use-after-free in visor... Or something. -- Pete ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!
