Problem with starting debugger in CVF 5.0

[paramont]

I am building a big project under Compaq-Digital Visual Fortran 5.0 A/D. This project can be compiled and linked ok. I can even run it for a little while. Then it will crash. So I want to debug it. but after I hit "F5", I was given an error message said: the instruction at "0x00000000" referenced memory at "0x00000000". The memory could not be "read". Click OK to terminate the program. Click CANCEL the debug the program. IF I click OK, the CVF will terminate, and shows another error message: The instruction at "0x6c371351"referenced memory at "0x00000004". The memory could not be read. Click OK to terminate the program. Then I click Ok, these will end CVF. Else if I choose CANCEL in the step above, I will enter a assembly language debugger window.

I have tried to reinstalled CVF, install CVF6.6, all doesn't work. My project also has a version under SUN SOLARIS, it works fine, and the dbx under SUN worked well. however, since we need a Windos version of it, we have to get through this.

Anybody has such experience that CVF's debugger will crash immediately after hit F5 in the CVF?

Thanks.

See if deleting the file in the project folder with a .OPT extension takes care of this.

I've never heard of this problem with DVF 5, but it happens with 6.x from time to time.

Thank you, Steve. That's really helpful. Now I can run debugger!
