[Bug 1453011] Re: SegvAnalysis: Failure: invalid literal for int() with base 16: '='

 

I think this output parsing bug bit me again today:

SegvAnalysis: Skipped: missing required field "Disassembly"
SourcePackage: gdm
Stacktrace:

This looks like a misalignment of the fields to me.

Title:
  SegvAnalysis: Failure: invalid literal for int() with base 16: '='

Status in apport package in Ubuntu:
  New

Bug description:
  Apport sometimes gets confused when analyzing a core dump:

      SegvAnalysis: Failure: invalid literal for int() with base 16: '='

  I'm attaching the crash file (sans base64-encoded core dump) that
  contains this and some other wonderful examples, like

      Registers: $6 = 0x0                                                                                                                         
      ThreadStacktrace: $9 = 0x4 <error: Cannot access memory at address 0x4>                                                                     
      Stacktrace: No symbol "__nih_abort_msg" in current context.

  and the Disassembly: field containing the actual stack trace, after
  the disassembly itself.
