I have been getting random hangs with recent Minefield builds on Centos5 x86_64 with 32bit Minefield builds and Flash 9 r124. I do have Flash restricted in terms of what it can write to the local disk. Attaching to the processing and breaking show stacks very similar to: #0 0xf72fff99 in JS_GetPrototype () from libmozjs.so #1 0xf78fc5f9 in gfxFlattenedPath::Release () from libxul.so #2 0xf78fd696 in gfxFlattenedPath::Release () from libxul.so #3 0xf7545633 in std::vector<unsigned short, std::allocator<unsigned short> >::resize () from libxul.so #4 0xf7545505 in std::vector<unsigned short, std::allocator<unsigned short> >::resize () from libxul.so #5 0xf752ff20 in std::vector<unsigned short, std::allocator<unsigned short> >::resize () from libxul.so #6 0xf7532388 in std::vector<unsigned short, std::allocator<unsigned short> >::resize () from libxul.so #7 0xf7540cd6 in std::vector<unsigned short, std::allocator<unsigned short> >::resize () from libxul.so #8 0xf753ca9f in std::vector<unsigned short, std::allocator<unsigned short> >::resize () from libxul.so #9 0xf7cb6b49 in NS_InvokeByIndex_P () from libxul.so #10 0xf779a82a in gfxTextRunFactory::Release () from libxul.so #11 0xf779a575 in gfxTextRunFactory::Release () from libxul.so #12 0xf7611be7 in std::vector<unsigned short, std::allocator<unsigned short> >::resize () from libxul.so #13 0xf7b27a08 in gfxMatrix::operator* () from libxul.so #14 0xf7b2606e in gfxMatrix::operator* () from libxul.so #15 0xf7b21ca0 in gfxMatrix::operator* () from libxul.so #16 0xf7b1e714 in gfxMatrix::operator* () from libxul.so #17 0xf7b1e8cf in gfxMatrix::operator* () from libxul.so #18 0xf0a0b68e in Flash_EnforceLocalSecurity () from .mozilla/plugins/libflashplayer.so #19 0x0b624218 in ?? () #20 0xeedb3800 in ?? () #21 0x00000000 in ?? () I have no idea why there is a null pointer at the bottom of the stack. bretr can also preproduce on Mac OS X although I have not been able to do so as of yet.

Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9pre) Gecko/2008042104 Minefield/3.0pre I'm sorry to say, but Adblock Plus 0.7.5.4 seems to be the culprit for my OSX hang. Once disabled, Flash seems to not be an issue.

This looks like the same stack as in 429903, duping.
