Internal GDB error

[David Frager <frager at nortelnetworks dot com>]

I am having problems running gdb in an AIX 4.3.3 environment.  I can set 
tracepoints, however, if I attempt to invoke any additional actions (i.e., step, 
next, etc.), I receive the internal gdb error below:

Any recommendations to help determine if this is a gdb bug or local environment 
issue would be appreciated.

My environment is:
AIX 4.3.3 running on a Motorola Powerstac
