D4GL extension name and correct running. What has to do one with the other?

Hello. Poltergeist exists! I have attached a simple program (a.4gl) that call our own C function varamb(). If I run the program with $ fglrun ./a.42r I have a memory fault(core dumped) when itexecutes the varamb function. If I run the program with $ fglrun ./a I works ok 1) What has to do bacon with speed ? 2) Any logical explanation, will be very much appreciated. - SCO 5.0.5 - D4GL 3.00.UC1 - SE 7.23.UC13 -- Evelio Martínez Tel: +34 96 337-95-80 Fax: +34 96 337-81-18
