My suggestion to you is to pull out your favorite debugger and
start looking at where the problem occurs. That usually provides
some clues or at least a basis on which you can start asking
questions that lead to a solution. If you have a follow-up question
as a result of this analysis, you should visit <http://cygwin.com/bugs.html>
for information on how to report bugs or ask for assistance with problem
analysis.

Hello, I would like to make you a question:
I'm trying to call to java code from C++ code, so I
have just do it for linux with gcc using gcj and gcjh.
Now, I have been trying the same for Windows 2000,
following these steps:
1.- Write the java file --> prueba_java.java
2.- Compile it with javac --> javac prueba_java.java
3.- Create the header file --> gcjh prueba_java
4.- Create the .o file -->
gcj gcj -c -g -O prueba_java.java
5.- Write the C++ file, from which I call the java
code --> main.cc
6.- Compile it --> gcc -c -I /MinGW/include main.cc
7.- Linking with java code -->
gcc -static main.o prueba_java.o -o ejecutable -L
-L/MinGW/lib -lgcj -lmingw32 -lwsock32
And when I try to execute the executable file (
ejecutable ), but it dies with an abnormal program
termination, because of the following error:
Program received signal SIGSEGV, Segmentation fault.

I would like you to tell me how to solve this problem,
if it's possible..
Thank you very much for your attention..
