[comp.lang.fortran] Error Messages

Hi folks;

Does anybody know where to find the explanation of the following error
messages. I couldn't find them in any SUN documentation.

*** IOT Trap = signal 6 code 0

*** Bus Error = signal 10 code 2

*** Segmentation Violation = signal 11 code 3

I'm running fortran in a SPARC 1, and the funny thing is that the first error
(IOT ...) happens only sometimes for the same run (same executable with same
input). I compiled the code to use the debugger and when I ran the program
everything went fine. Any clues on what may be going on?. My first compilation
was using the -O (optimizer) option. My next steps are to compile with the -O2,
and then the -O1 options and see if this still happens.

Thanx in advance,

Martin

I'm new to Fortran and would like some help with on the following error
messages.  I would like to know what they mean (using MIPS F77):

1. common misalignment of "lprint"
2. Declaration error declaration among executables
3. Execution error unclassifiable statement

Thanks in advance.
Stephen.
