            Bug ID: 20793
           Summary: gdb causes Segmentation fault in simple program
           Product: gdb
           Version: 7.12.1
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: dennisschaefer at gmx dot net
  Target Milestone: ---

Created attachment 9613
  --> https://sourceware.org/bugzilla/attachment.cgi?id=9613&action=edit
program to trigger the bug

Please see the attached c program. 

Compile it with 
gcc -o stack_overflow_example_1 stack_overflow_example_1.c

Running the program without gdb like ./stack_overflow_example_1 AAAA
works just fine. 

By execution the program with gdb instead it results in a Segmentation fault.

gdb ./stack_overflow_example_1 AAAA
