Problem to let debugger stop at the crash point

[paramont]

I tried use ISNAN. It compiled ok, but when I ran it, it crashed immediately, with the error message of:
First-chance exception in f2d.exe: 0xC0000005: Access Violation.
The thread 0x58C has exited with code -1073741667 (0xC000009D).
The program 'C:francf2dDebugf2d.exe' has exited with code -1073741667 (0xC000009D)
And the debugger can't stop at the point where my project crashed.

Could you please tell me about these messages?

Thanks.

What version of Visual Fortran do you have? See my response in your NaN topic regarding access violation. The debugger should stop automatically...

I am using CVF 5.0A

1. Make sure to upgrade to 5.0D

2. You have to define environment variable FOR_IGNORE_EXCEPTIONS=TRUE*. On Win2k, it is in My Computer/Properties/Advanced/Environment variables. On Win9x, you should add it to Autoexec.bat

Another option in 5.0 is Debug..Exceptions and then change the action for Access Violation to "Stop Always". This isn't needed in 6.0 and later.
