Possible bug with ddd and AIX

[Lia Pennington]

My developers would like to use ddd-3.2.1 on a AIX 4.3.3 system,
However after I compile it using gcc-2.95.2 and run it with "make
check", 
I get the "Oops! You have found a bug in ddd" message.

The following is some detail that I hope helps.... -Lia

I first compiled ddd with "LDFLAGS =  -Wl,-bbigtoc" and got
the following message when compilation finished:
> ld: 0711-783 WARNING: TOC overflow. TOC size: 107804    Maximum size: 65536
>         Extra instructions are being generated for each reference to a TOC

I added CXXFLAGS=-mminimal-toc which fixes this, but either
way I receive the following error message after running
"make check" or trying to debug our code:
