Details

* TITLE/SUMMARY Lou's Fishcam (auto-updating JPEGs) crashes Viewer * STEPS TO REPRODUCE 0) View http://home.netscape.com/fishcam 1) Click on any of the links to auto-updating Fishcam views (Camera 1-3, either large size or small size.) * RESULT - What happened Dr. Watson; 100% reproducibility. (viewer.exe, access violation.) - What was expected No crash; fish cam updated. The crash may be related to the heavy JavaScript used on the page (which has its own problems). For a greater sample size, I also checked http://events.exploratorium.edu/CAM2/ While a crash didn't occur, Viewer was immediately cripped (no updates to content region, including on resizes), but not crashed. (It would still access other URLs.) * REGRESSION - Occurs On viewer.exe (12.30.98 Win32 build used) - Doesn't Occur On Communicator 4.5 for Win32 (RTM Complete build used) IE 4.0 for Win32 (had its own problems with the script, but different ones..) * CONFIGURATIONS TESTED - Windows NT 4.0 SP 3, 96 MB RAM.

Gagan -- this is crashing in Netlib, so it's all yours. Here's the stack trace: FE_SetRefreshURLTimer(MWContext_ * 0x00943100, URL_Struct_ * 0x00940910) line 428 + 12 bytes net_CallExitRoutine(void (URL_Struct_ *, int, MWContext_ *)* 0x004a2b2e bam_exit_routine(URL_Struct_ *, int, MWContext_ *), URL_Struct_ * 0x00940910, int 1, int 102, MWContext_ * 0x00943100) line 1138 + 13 bytes CallExitRoutineProxyEvent::HandleEvent(CallExitRoutineProxyEvent * const 0x0094e230) line 860 + 40 bytes ProxyEvent::HandlePLEvent(PLEvent * 0x0094e234) line 374 PL_HandleEvent(PLEvent * 0x0094e234) line 395 + 10 bytes PL_ProcessPendingEvents(PLEventQueue * 0x008f9410) line 357 + 9 bytes _md_EventReceiverProc(void * 0x003602ca, unsigned int 49336, unsigned int 0, long 9409552) line 675 + 9 bytes USER32! 77e71250()

Well...the web cams still are totally munged, at least they don't crash anymore (1.25.99 build on Linux, and 1.26.99 build on Mac OS 8.5 and Win NT 4sp3, so it's fixed for me ;) {"totally munged" := never updated, on Linux (fishcamsmall3), repeated twice with garbage underneath, etc. Will research and write up as separate bug if appropriate.}
