system() retuens -1

[Ahmed Moustafa]

I call external programs with system(). It used to return the correct value
i.e. zero if there is no error and a non-zero value otherwise. Recently, it
always returns -1 even if the external programs work fine. What could be the
reason?

Thanks in advance,

Ahmed
