int main ()

printf("hello");
return 0;

Ok, I compiled the code.c with the cygwin gcc
C:\Documents and Settings\Rafa\Desktop>gcc code.c -g -o program.exe
I ran the cygwin gdb
C:\Documents and Settings\Rafa\Desktop>gdb program.exe

Then if I run the program (without any pause or breakpoint), the programs
runs well
(gdb) r

hello
Program exited normally.
But if I put a breakpoint in the main function, I get the segmentation fault
message, even I try to continue.
(gdb) break main

Yes, I have NOD32 antivirus and Comodo firewall, but I also have NOD32 and
Comodo firewall in the desktop pc and I don't have any problem with gcc or
gdb.
Yes, I have installed in this pc (laptop) the Logitech webcam software and
this is not installed in the desktop pc (I don't have any webcam on that
pc), but could be it the cause of the segmentation fault?
