problem with runningsimple C program

problem with runningsimple C program

[Milos Puzovic]

I was trying to run the following simple C code:

void func();

main() {
   func();
   }

void func() { printf("Hello world from func()!"); }

First, I compiled it with gcc program.c -o program. Then I tried to run 
it, but I got "Segmentation fault (core dumped)" message.

The version of gcc is 3.2 20020927 (prerelease).

Best wishes,
Milos.

i.e. WFM. BTW, use "int main() { ...; return 0;}" - even in test code.

As you can see the amount of characters printed in func() gets sent as exit
code.
Did you expect that? ;-)

Works for me. Have you oversimplified this example?

Strange! I have just reinstalled whole cygwin, compiled the code and it 
was working. Still don't know what was the problem.

Milos.
