--- Comment #19 from Eugene <ken20...@ukr.net> --- Yes, it seems several crash happens during debugging. But Firefox not closed. And at last I reached the crash that happens after closing Firefox. But if several crashes happens before the crash closing Firefox, how it could be possible to backtrace it ? If I try to run bt/bt full immediately after first segmentation fault, it writes the following: #0 PatchJump (label=..., jump=...) at /build/buildd/firefox-31.0+build1/js/src/jit/x64/Assembler-x64.h:716 No locals. #1 js::jit::JitRuntime::patchIonBackedges (this=<optimized out>, rt=<optimized out>, target=target@entry=js::jit::JitRuntime::BackedgeLoopHeader) at /build/buildd/firefox-31.0+build1/js/src/jit/Ion.cpp:412 iter = {iter = 0x7fffb95d1de0} #2 0x00007ffff32cab85 in js::jit::InterruptCheck (cx=0x7fffdeb54480) at /build/buildd/firefox-31.0+build1/js/src/jit/VMFunctions.cpp:523 No locals. #3 0x00007ffff7e5527a in ??
