Crash using '-stack-list-frames'

Crash using '-stack-list-frames'

[Srinath Avadhanula]

Hi,

Gdb is crashing on me when I try to use the command 'interpreter mi
"-stack-list-frames 0 182"'. I debugged gdb using gdb and found that
it gets into an infinite recursion with the first few frames being as
below.

Unfortunately, I am unable to come up with a simple test program which
reproduces the problem. I would be glad to help further if given any
pointers.

The version of gdb I am using is:

This is the C++ name demangler.  Set a breakpoint at it and find what
input is taking it to this recursion?
