I hit this assertion failure when trying to play a Hulu video on Windows with a debug build I downloaded from mozilla-central. I tried to bisect this is problem with mozregression to see if it was a regression, but the assertion failure was not reproducible when firefox.exe was launched by mozregression. Nick Fitzgerald said this assertion failure might be related to FastConvertYUVToRGB bug 1232854. STR: 1. In a debug Windows build, open http://hulu.com/watch/13947 RESULT: Assertion failure: mRawPtr != 0 (You can't dereference a NULL RefPtr with operator->().), at c:\builds\moz2_slave\try-w32-d-00000000000000000000\build\src\obj-firefox\dist\include\mozilla/RefPtr.h:297 #01: JS::ubi::DominatorTree::root[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x1aff6e0] #02: mozilla::LoadInfo::TriggeringPrincipal[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x47f7b8] #03: mozilla::LoadInfo::TriggeringPrincipal[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x47ab2d] #04: mozilla::LoadInfo::TriggeringPrincipal[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x47b2f9] #05: mozilla::LoadInfo::TriggeringPrincipal[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x4b0b96] #06: mozilla::LoadInfo::TriggeringPrincipal[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x47f774] #07: mozilla::LoadInfo::TriggeringPrincipal[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x47f72c] #08: mozilla::LoadInfo::TriggeringPrincipal[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x47f476] #09: JS::ubi::DominatorTree::root[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x1d8fb3d] #10: JS::ubi::DominatorTree::root[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x1de4225] #11: workerlz4_maxCompressedSize[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x25573e0] #12: XRE_GetFileFromPath[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x25a1f07] #13: XRE_GetFileFromPath[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x25a033b] #14: XRE_main[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x25a2d68] #15: ???[C:\Users\cpeterson\Desktop\firefox\firefox.exe +0x25de] #16: ???[C:\Users\cpeterson\Desktop\firefox\firefox.exe +0x1edc] #17: ???[C:\Users\cpeterson\Desktop\firefox\firefox.exe +0x2966] #18: ???[C:\Users\cpeterson\Desktop\firefox\firefox.exe +0x4d09] #19: BaseThreadInitThunk[C:\WINDOWS\SYSTEM32\KERNEL32.DLL +0x138f4] #20: RtlUnicodeStringToInteger[C:\WINDOWS\SYSTEM32\ntdll.dll +0x65e13] #21: RtlUnicodeStringToInteger[C:\WINDOWS\SYSTEM32\ntdll.dll +0x65dde]
The symbols don't look right at all here. Are you able to trap it in a debugger and use the symbol server?

Unfortunately, I can't right now. I don't have a debug environment on my Windows VM.

This call is not plausible: #10: JS::ubi::DominatorTree::root[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x1de4225] #11: workerlz4_maxCompressedSize[C:\Users\cpeterson\Desktop\firefox\xul.dll +0x25573e0] DominatorTree::root is an internal piece of the devtools, and is certainly never called from something concerned with compressed data. This could be bad symbols or a corrupt stack, but it probably can only be debugged if we can reproduce it.
