Status: RESOLVED FIXED

Description

[Benjamin Smedberg]

The minidump_stackwalk program on staging is returning unexpected results which causes odd exceptions during processing:

runProcessor for f29da7b3-3a19-11dc-80d9-001321b0783d
Caught Error: exceptions.ValueError
need more than 5 values to unpack
  File "/opt/breakpad_source/processor/socorro/lib/monitor.py", line 117, in runProcessor
    processor.process(dir, dumpID, report)
  File "/opt/breakpad_source/processor/socorro/lib/processor.py", line 58, in process
    report = self.processDump(dumpPath, jsonPath, dumpID, report)
  File "/opt/breakpad_source/processor/socorro/lib/processor.py", line 71, in processDump
    threads = report.read_stackframes(fh)
  File "/opt/breakpad_source/processor/socorro/models/__init__.py", line 546, in read_stackframes
    (thread_num, frame_num, module_name, function, source, source_line, instruction) = map(EmptyFilter, line.split("|"))

To diagnose, can you please run the following command and attach the output to this bug?:

First find f29da7b3-3a19-11dc-80d9-001321b0783d.dmp, which should be in the directory configured to save failed dumps. If we're not saving failed minidumps, I can attach one to the bug.

/path/to/minidump_stackwalk -m /path/to/f29da7b3-3a19-11dc-80d9-001321b0783d.dmp /mnt/socorro/symbols/symbols_ffx /mnt/socorro/symbols/symbols_os

I recompiled the minidump_stackwalk binary, as per luser's recommendation, and it doesn't sigsegv now.
