when the program stops at the "break main" you can't see them, but after a "next" you can. Job was executed on host(s)

For me if the program doesn't uses argc/argv the values are optimized out (even if specifying O0). Now, I won't argue that C++ isn't a high-level object-oriented programming language since every book on the subject is careful to point out the opposite. I'll leave this question unansvered...
If no error message is generated or if the message is insufficient one can use a debugger to manipulate and inspect the code as it is running to identify the nature skie_knite007 Programming 2 05-14-2005 12:12 AM main(int argc, char **argv) Longinus Programming 4 06-12-2004 08:22 AM argc argv linuxanswer Programming 8 10-25-2003 08:54 PM All times are GMT -5. Other useful debuggers While gdb is good for common problems with serial code, it doesn't help debug more complex problems like parallel bugs and subtle memory errors. It will instantly tell you where the segfault is.
I think your gdb is invalid.

That way that variable will be statically allocated by the linker in the data section, and you'll have no problem with the stack. To debug it in gdb: First compile: [[email protected] bugs]$ f90 -TENV:simd_zmask=OFF -TENV:simd_imask=OFF -TENV:simd_omask=OFF -O0 -g bugs.f90 Now start the debugger, specifying the program we want to debug: [[email protected] bugs]$ gdb a.out

Someone thoughtfully blames differences in system libraries. I can't show you because to run your code one needs files which you did not provide. Argc= Error Reading Variable Finally, depending on the compiler and how it is called in the default environment, a program may not stop and issue a SIGFPE after doing something non-sensical.

Keep it up. If I compile a simple "int main(int argc, char *argv)" program with -g, and debug with gdb, I'm getting an error when I break at the start and try to print This is a lot of memory in one stack frame, and possibly more than your environment allows for the entire stack.

They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

If you use argc/argv, then their values are reports as normal. But, in any case: if you haven't already, invest time learning how to use gdb. #7 9th February 2008, 10:48 PM philstewart Offline Registered User Join Date: Nov The time now is 01:36. The stack is for temporary and little operations, to avoid overhead of heap memory allocation, as allocating memory in the stack is just a stack pointer adjustment (e.g.
