[Bug 160999] Re: Apport doesn't overwrite existing core files

[Michi Henning]

And nearly 13 years later, we are still here.

If I have a core file in the Current directory and another run of the
program encounters a fault, the old core (possibly months old) prevents
the current core file from being written. Outstanding!

Title:
  Apport doesn't overwrite existing core files

Status in apport package in Ubuntu:
  Confirmed

Bug description:
  While debugging some code, I noticed that existing core files aren't
  being overwritten when they should be.  According to core(5), the
  following file should be overwritten, but it's not:

  bam:/tmp$ id -un
  gerald
  bam:/tmp$ ls -l core
  -rw------- 1 gerald gerald 3407872 2007-10-30 21:22 core
  bam:/tmp$ date
  Thu Nov  8 09:36:23 PST 2007
  bam:/tmp$ ./coretst 
  Segmentation fault (core dumped)
  bam:/tmp$ ls -l core
  -rw------- 1 gerald gerald 3407872 2007-10-30 21:22 core

  Creating the initial core file works fine:

  bam:/tmp$ rm core
  bam:/tmp$ ./coretst 
  Segmentation fault (core dumped)
  bam:/tmp$ ls -l core
  -rw------- 1 gerald gerald 163840 2007-11-08 09:36 core
  bam:/tmp$ date
  Thu Nov  8 09:36:49 PST 2007
