Hi,

I'm trying to use gdb version 4.6 to debug C++ code generated by Sun
C++ version 2.1. I'm using an Sun ELC with SunOS 4.1.2 generic kernel.

Please send a reply so I know that you have recieved my letter and if
it is a known problem, how can I proceed. Unfortunally I can not use
'gcc -x c++', I have to use Sun CC. This problem did not exist in gdb
4.0 but the support for C++ was not to good in gdb 4.0, I was hopping
to use gdb to debug C++ code.

Below is a sample of what causes gdb to core dump:
