This is an offshoot of bug#6177, which got a bit diluted with different reports of start-up crashes. This bug is specifically for start-up crashes in raptorgfxwin.dll. It appears to happen only on slower (~P133Mhz) win95 machines. Personally, the crash appears more than half the time on my machine. Talkback Incident ID# is 8874953 (link above). Here is the stack trace, which is from a 5/20 build.

Marking M6 since 6177 is marked M6. BTW, this happens on Apprunner.

I'm seeing this crash about 20% of the time on a faster (233 MHz) Win95 machine.

*** Bug 6407 has been marked as a duplicate of this bug. ***

I found a machine that was failing nearly 100% of the time. It was a pentium 100Mhz running WIN95. I installed VisualC++ Ver5.0 to debug the problem. After installing VisualC++ apprunner ran reliably 10 out of 10 times. VisualC++ installs a large number of dll's. I suspect it upgraded some of the OS dll's that "Gecko" uses. The following is a list of all of the dll's that were touched. We need to determine which dll's in the list are required to stop the apprunner crashes.

The only ones that look vaguely familiar are _WUTL95.DLL and mfc42.dll Can you stick these two files somewhere and I'll try them out?

I shared my drive. Machine name is Kmcclusk-vl. Directory is dll. I put all of the dll's in the list in there. The dll's include all of the dll's that "Seamonkey" installs as well as the dll's that VisualC++ installs.

mfc42.dll and _wutl95.dll are the only non-seamonkey dll's that I had on my system. I replaced them with your files, and I'm still able to crash on start-up. Hmmmm.

This happens on my Compaq Deskpro 5133 more than 50% of the time too. Most recent build 1999052408.

I've been asked to investigate this further with a stock Windows 95 machine (Compaq P90). I expect to have some preliminary results by the end of 26-May-99.

The talkback reports indicate that nsTitledButtonFrame::DisplayAltFeedback is passing a null pointer to aRenderingContext.DrawImage. This is why it is crashing. I will put a check for a null image pointer after the call to LoadIconImage which should stop the crash. The question remains as to why LoadIconImage sometimes comes back with a null pointer. void nsTitledButtonFrame::DisplayAltFeedback(nsIPresContext& aPresContext, nsIRenderingContext& aRenderingContext, PRInt32 aIconId) ... #ifdef _WIN32 // Display the icon nsIDeviceContext* dc; aRenderingContext.GetDeviceContext(dc); nsIImage* icon; if (NS_SUCCEEDED(dc->LoadIconImage(aIconId, icon))) { if (nsnull != icon) { // New check to stop bug #6934 Frequent (~20%) crashes in raptorgfxwin.dll aRenderingContext.DrawImage(icon, inner.x, inner.y); // Reduce the inner rect by the width of the icon, and leave an // additional six pixels padding PRInt32 iconWidth = NSIntPixelsToTwips(icon->GetWidth() + 6, p2t); inner.x += iconWidth; inner.width -= iconWidth; NS_RELEASE(icon); } } NS_RELEASE(dc); #endif ...

Does LoadIconImage load the images for the toolbar? I often notice that one (I don't think I've ever seen more than one) of the buttons in the toolbar shows up with a broken image icon - usually forward or back, maybe print or some others. Could this be related? The missing icons have happened before the crash started, though.

I checked in the patch to check for the null image. I need someone to try pulling and testing on a platform that was failing to confirm that it fixes the apprunner crashes. I don't have access to a platform that is failing.

I will check this when we get builds, supposedly this evening, unless you can point me to the particular file you updated. I don't have my win95 machine set up to build.

marking fixed so this gets some testing... kmcclusk still has some investigation to do on why DrawImage is being passed a null image in nsTitledButtonFrame::DisplayAltFeedback (we should open another bug for that...) but the patch should reduce the start up crash noise (86 crashes in the past few days) and help us to find the next round of problems elsewhere in the startup sequence

*** Bug 7021 has been marked as a duplicate of this bug. ***

Okay, I've now started up 40 times without crashing. Marking verified fixed. I also see that kevin filed the bug to himself about the null pointer showing up in the first case.

Moving all Apprunner bugs past and present to Other component temporarily whilst don and I set correct component. Apprunner component will be deleted/retired shortly.
