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.

Thanks a lot Norbert Wed, 18 Jun 1902 08:00:00 GMT Dick Hendrickso#2 / 3 bus error As I recall, bus error is usually Unix's way of signaling a bad address.
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.

Contents 1 Causes 1.1 Non-existent address 1.2 Unaligned access 1.3 Paging errors 2 Example 3 References Causes There are at least three main causes of bus errors: Non-existent address Software instructs Accordingly, the CPU sets this physical address on its address bus and requests all other hardware connected to the CPU to respond with the results, if they answer for this specific i will try use pointer represent ,try use free () to release the memorary . share|improve this answer answered Apr 12 '11 at 23:27 Amadan 93.4k887135 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign
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.
accessing a memory-mapped file or executing a binary image which has been truncated while the program was running), or because a just-created memory-mapped file cannot be physically allocated, because the disk Unfortunately, when a program encounters one of the three errors described above, no reference is made to the source of the problem in your code. 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.
bus error in J62, J7 on HPs, Suns 2. Click Here to join Tek-Tips and talk with other members! That should get rid of any alignment problems. This happened quite a bit with the older SGI compilers (from IRIX 5.3 days and before).
