One method is to use printf() statements to determine how far the program is getting before it crashes, and to print out the contents of interesting variables. Register now while it's still free! real foo(10,5) integer i, j call foobar(foo,i,j) <-- real,int,int | |==> these don't match! | subroutine foobar(dummy,idummy,jdummy) <-- double,int,int double precision dummy(10,5) integer idummy, jdummy An arithmetic or floating point exception I use F77 on a SGI unix.

To debug it yourself next time, compile with -g option, like this: $ gfortran -g code.f95 and run it under a debugger: $ gdb a.out gdb> run it will then give This is an example of register indirect addressing. A bus error occurs if the data sets passed during a main/subprogram to subprogram interface are not of equal size.

Paging errors[edit] FreeBSD, Linux and Solaris can signal a bus error when virtual memory pages cannot be paged in, e.g.

This is because 1+E1000 is greater than the value that can be represented by a real variable. I'm running gfortran (not sure which version, off-hand) from the terminal in OS X. Attempting to access a unit larger than a byte at an unaligned address can cause a bus error. Join Us! *Tek-Tips's functionality depends on members receiving e-mail.

so i think data in the common block is not resetted before cycle . Core dumps created this way will not take up quota, and they will automatically vanish when the machine is rebooted. I spent the time of several people on such a situation, where an array over-run clobbered the stack. How do you combine the elements in Sheldon's T-shirt?

Why do solar planes have many small propellers instead of fewer large ones? A segmentation violation occurs when some part of your code attempts to access a part of memory that is not defined by your program. Bus Error? 4.

Systems tolerate this inefficient algorithm, as it is an essential feature for most software, especially string processing.

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 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

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)).
