runtime error

[xizhang]

The messagne when I run the code

Debug assertion failed!

program:
File: winsig.c
line 419

Expression: ("invalid signal or error ", 0)

I use windows version 11.1.

The file winsig.c would appear to be a C program - not a Fortran program
:-)

That's a handler in the C runtime. Intel Fortran programs may end up there when something goes wrong - pehaps like an unhandled floating point exception or similar. The original poster needs to provide (lots) more information.

(I don't know what causes execution to specifically end up there (what combination of compile options etc) - but it is a place my programs also like to visit occasionally.)
