I'm afraid it is simply broken:
- system("notepad.exe") works OK
- system("bash.exe") crashes in the way mentioned in earlier e-mails
- system("example.bat") do not crash if example.bat do not start DJGPP program but crashes if it 
starts DJGPP program (crash backtrace shows initial program in this case)

I'm not sure whether its is possible to fix it.
