Bus Error 10 Fortran

Another possible cause is an argument list in a call statement that does not contain the same variable types as the subroutine declaration. How does the Mac SE/30 send video to the analog board? To answer your question "what is a bus error?" : it generally means that your program tried to access a nonexistent address, or an address that doesn't have the proper alignment Fri, 04/08/2016 - 08:09 Hi all, I'm running a pretty heavy MPI application (the WRF model) on Linux and get a BUS error (please see below the output for the type http://patricktalkstech.com/bus-error/bus-error-fortran.html

said on Thu, 07/23/2009 - 09:52 Thank you for pointing these out. Unlike bytes, larger units can span two aligned addresses and would thus require more than one fetch on the data bus.

Is there oscillating charge in a hydrogen atom? Arrays in Fortran must have integer subscripts whose values are between 1 and the dimension of the array the subscript refers to.

i still not find a way to do this. How to typedef the return type of a member function from a template class? Why secure web services? How far above a waterfall should you be to safely cross?

command statement return end the command statement should be ok . The three most common errors are segmentation violations, bus errors, and arithmetic exceptions. c_number = 1000 ! ... That's because FORTRAN implicitly passed everything by reference, including constants (!) –Dan Breslau Dec 13 '10 at 12:19 Actually, great catch.

Different RAID settings for different folders on the same logical drive Do paper books exist in the 5th ed. In general heap and stack are competing for the same physical memory resources.

  1. We know nothing about row and column values...
  2. In modern use on most architectures these are much rarer than segmentation faults, which occur primarily due to memory access violations: problems in the logical address or permissions.
  3. Why is nuclear waste more dangerous than the original nuclear fuel?

However, I would like to add another cause which actually happend in one of my applications. Similarly, if multi-byte accesses must be 32-bit aligned, addresses 0, 4, 8, 12, and so on would be considered aligned and therefore accessible, and all addresses in between would be considered I'm running gfortran (not sure which version, off-hand) from the terminal in OS X. Source For a good comment about bus error, see Segmentation fault.

Just move the line ALLOCATE(temparray(numrolls)) before you enter the loop. It provides a quick and easy way to find such errors in your source code. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.

Two tails in a row - what's the probability that the game started with a head? RE: Bus error 10 xwb (Programmer) 23 Jul 12 18:59 Why not put your entire common block into a file (including real/integer declarations) and include these files instead of replicating the This trace back report is read from the bottom of the list upwards.  Find the uppermost subroutine or function from your code along with it's line number to isolate which instruction When I run the program it stops in a function which was worked through before very often (at least 47x12000x8 times) with a bus error.

RE: Bus error 10 momphy (Programmer) (OP) 25 Jul 12 18:30 @xwb acturally , that's what i do . have a peek here 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.

If you are unable to locate the offending source code, you should use the dbx debugger.
