it's correct . Then if the compiler choses a naive packing of the variables in memory, the double x will be offset by 4 bytes, and usually will cause a bus error, though the Just for a sanity check, find a system exerciser - perhaps a LINPACK or some other memory/cpu intensive app and run it for a day to stress the system.

It is possible for CPUs to support this, but this functionality is rarely required directly at the machine code level, thus CPU designers normally avoid implementing it and instead issue bus Only really useful for debugging the GNU Fortran compiler itself. -fdump-fortran-optimizedOutput the parse tree after front-end optimization. Replacing it with a declared INTEGER in the call, seemed to do the trick! I don't see how I'm pointing to non-existant memory.
For example, for hardware based on the IBM System/360 mainframe, including the IBM System z, Fujitsu B8000, RCA Spectra, and UNIVAC Series 90, instructions must be on a 16-bit boundary, that Do paper books exist in the 5th ed.

C and C++ programmers can also use 'gdb'. list is a (possibly empty) comma-separated list of the following exceptions: ‘invalid’ (invalid floating point operation, such as SQRT(-1.0)), ‘zero’ (division by zero), ‘overflow’ (overflow in a floating point operation), ‘underflow’ I don't know modern FORTRANs, but I know that with earlier versions of FORTRAN, you could crash a program like that by passing in a constant (e.g., by calling p_list(0, my_matrix)).

If you need to debug your program, you may want to enable a core dump. The first three exceptions (‘invalid’, ‘zero’, and ‘overflow’) often indicate serious errors, and unless the program has provisions for dealing with these exceptions, enabling traps for these three exceptions is probably Or have you passed a non-character argument to a character dummy? check my blog Formats statements are very common in fortran, so get some familiarity with that with the compiler manual. –ifeitosa Apr 13 '11 at 4:11 add a comment| up vote 4 down vote
Not the answer you're looking for? An arithmetic exception can also occur if the value of a variable exceeds the largest value that can be represented by the corresponding data type. I've isolated it to simply this assignment. Not the answer you're looking for?
