            Bug ID: 19424
           Summary: frequent core dump
           Product: gdb
           Version: 7.10
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: faorg-lists at yahoo dot co.uk
  Target Milestone: ---

gdb process terminated with a core dump.
Closing this gdb session.

I haven't been able to identify the steps to reproduce, but it happens
frequently debugging a cpp program linked against Fortran libs (gcc 4.8.3,
Intel ifort 13.0.1 20121010).

The core file contains this:

Running on Linux version 3.14.4-100.fc19.x86_64. gdb 7.10 compiled from your
source.  I have had similar problems with several older versions.
