Hey @phosek, @delcypher and I noticed that a Swift+ASan test is failing due to llvm-symbolizer crashing like this:

  (gdb) bt
  #0  0x00007f6c3adbae97 in raise () from /lib/x86_64-linux-gnu/libc.so.6
  #1  0x00007f6c3adbc801 in abort () from /lib/x86_64-linux-gnu/libc.so.6

  #8  0x000000000040cff2 in main ()

Based on the history I thought I'd ping this patch (although I'm not sure I spot an unchecked error). Any help appreciated.
