Stability Report


  • Due to a file name pattern change by Adobe, the version of current Flash releases isn’t detected by Socorro (bug 742735). This also makes KaiRo’s Flash crash/hang reports not list those 11.2.* versions – a fix is ready for landing and should be deployed in tomorrow’s Socorro release.



  • bug 741715 crash in XPCWrappedNativeProto::TraceJS
  • bug 743767 Firefox crash @ memcpy | GlyphBufferAzure::Flush


  • bug 744043 Firefox crash [@ gfxASurface::GetType()


  • bug 717175 – gfxFont::AgeCacheEntry. Fixed in 12b4.
  • bug 673543 – nsDiskCacheMap::DeleteRecord. Patch waiting review.
  • bug 738661 – crash in nmsvc from CovenantEyes. Trying to repro in a debugger.
  • bug 741179 – crash in nsDiskCacheBlockFile::Write. Met this morning to discuss. Looking at correlations more closely, trying to reproduce.

Third Party

  • bug 743699 Flash crash in 11_2_202_228
    • After we reprocess signatures there will likely be more bugs related to this Flash version filed
