1.5.19-4: Problem to debug dll-mechanism on Cygwin

[vita@unileoben.ac.at]

Greetings!

I run into some strange problems while trying to debug a simple application in
order to test dll-mechanism with Cygwin 1.5.19-4 on Windows 2000 Professional.
The whole minimalistic application, made of "a.cpp", "a.h" and "main.cpp", is
attached and was compiled using "compile.sh" script. If I try to debug this
program with gdb, I am running to some strange problems, however applications
alone seems to work properly. I tested it under Linux and found no problems.

gdb output:

welcome to change it and/or distribute copies of it under certain conditions.
Type "show copying" to see the conditions.

This GDB was configured as "i686-pc-cygwin"...
(gdb) run

(gdb)

Can somebody try it and tell me what I am doing wrong or what happens here?

Sincerely Yours,

PV
