nogc "works" -- always the WinContext/PushPixmap assertion failure<BR>
<BR>
paranoidgc is broken the same as default -- variety of assertion failures and access violations<BR>
Including but NOT limited to:<BR>
<BR>
***<BR>*** runtime error:<BR>*** <*ASSERT*> failed.<BR>*** file "..\src\runtime\common\RTCollector.m3", line 1708<BR>***<BR><BR>
<BR>
which is in RefSanityCheck, doesn't look useful.<BR>
<BR>
still many access violations at 00200000-4.<BR>
I think 00200000 just happens to be some pixmap data from the splash screen that clobbered some other data but I don't know.<BR>
I posted a big hex dump the other week to see if anyone could confirm it looks like pixmaps.<BR>

<DIV>I just tried these options. Here are results:</DIV>
<DIV> </DIV>
<DIV>recent cm3 on XP: paranoidgc yeilds assert in RTCollector.m3 line 1706, while nogc gets assert in WinContext.m3 line 165. I note that the juno window begins drawing before the crash on nogc whereas it does not on paranoidgc.</DIV>
<DIV> </DIV>
<DIV>recent cm3 on Vista, same results as above except that it appears to reference an illegal memory location before hitting the assert in the RTCollector when using paranoidgc.</DIV>
<DIV> </DIV>
<DIV>old d5.7.0 circa August 2008 on XP: paranoidgc gets a repeating assert at line 845 in ThreadWin32.m3. You have to hit Ctrl-C to abort the repeating error message. Not sure if anything else happens first because it scrolls too far. For nogc, we get same behavoir as the other tests above.</DIV>
<DIV> </DIV>
