>Organization:
>Environment:
Linux Redhat 7.3, gdb5.2.1 compiled using gcc-3.1.1, binutils-2.12.1 - Which is probably a fairly oddball setup, let me know if you want some more tests....
>Description:
The p command enters an infinite loops that consumes all memory. May be the same as bug 601?
>How-To-Repeat:
Compile and debug the attached 4 line c++ program.
b 'main'
run
Step until just past the   
  a << "blah";

Then 
  p a

Computer then freezes until linux's Out Of Memory killer kills gdb.

Dunno
