  Hi Johann,
  
  Excerpts from Johann Klähn's message of 2012-04-18 13:58:24 -0700:
  > After sucessfully importing several messages I now run into this every
  > time I try to import mails from gmail. (It does not crash on the same
  > message every time. Perhaps the offending message is marked as seen
  > before the crash happens and thus is skipped the next time.)
  
  Thanks for the report. This appears to be a crash in leveldb-ruby. I
  should be prepping a new release shortly that might fix this problem
  (there have been random leveldb bugfixes in the mean time, though I'm
  not sure if any of them are particular to this problen).
  
  Since you can reproduce this, can you try running this command through
  valgrind or gdb and seeing if that points to anything interesting in the
  crash? For extra credit, check out the leveldb-ruby project, recompile
  it with debugging turned on, and then run it through valgrind.
  
  If this isn't fixed with the latest leveldb code, then we'll have to
  send the bug report upstream to them.
  
  I'm leaving the rest of your report in for the list:

    Hi William,
    
    after running gdb I found the following on the debian bug tracker
    (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=627818 on a bug
    related to ffmpeg):
    
    eglibc (2.13-3) unstable; urgency=low
      Starting with version 2.13, eglibc provides an SSSE3 optimized version
      of memcpy() on the amd64 architecture. This version might copy memory
      backward in some conditions, which causes issues if the source and
      destination overlap. memmove() should be used in such cases, but some
      programs still wrongly use memcpy().
    
    The cause of the segmentation fault seems to be the call to memcpy()
    in PosixMmapFile::Append(leveldb::Slice const&) in
    leveldb/util/env_posix.cc.
    Please note that I am indeed on amd64 (and using glibc 2.15).
    
    Best wishes,
    Johann
    
    Stack trace follows:

      I just tried this again and the source of this problem does not seem
      to be memcpy vs memmove but that Append tries to copy data to
      unallocated memory.
      Note below that limit_ points to a string "wp/labels". This may
      indicate a stack overflow, I guess (Though I'm not too proficient in
      debugging C++).
      
      My test machine is running x86_64 (intel), ruby 1.9.3p194 and
      leveldb-ruby built from git HEAD.
      
      Program received signal SIGBUS, Bus error.
