Tim P. Problems with HP-Oberon (Bus Error) 5. For example, if multi-byte accesses must be 16 bit-aligned, addresses (given in bytes) at 0, 2, 4, 6, and so on would be considered aligned and therefore accessible, while addresses 1, 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.

One possible cause of this problem is an unequal number of arguments in the argument list of a 'call' statement and the corresponding subroutine declaration as in: call foobar(x,y,z) <-- 3 Norbert: A bus error is usually something you get when you have some misaligned data. Replacing it with a declared INTEGER in the call, seemed to do the trick! Say for example you have a common block common /x/ i,x(10),j,y(20) where i,j are default sized integers (4 bytes) and x and y are double precision (default

The following Fortran code is giving me a bus error on my Mac but no errors when I run it on my Linux machine: PROGRAM TINY WRITE(UNIT=*, FMT=*) ‘Hello, world!' END Trying to write to program memory would more likely cause a segmentation fault. Dick Hendrickson Quote: > Hi there, > I have to write some functions to an allready existing program. have a peek at these guys accessing a memory-mapped file or executing a binary image which has been truncated while the program was running),[2] or because a just-created memory-mapped file cannot be physically allocated, because the disk

You may redistribute copies of GNU Fortran under the terms of the GNU General Public License. SIGBUS can also be caused by any general device fault that the computer detects, though a bus error rarely means that the computer hardware is physically broken—it is normally caused by That's because FORTRAN implicitly passed everything by reference, including constants (!) –Dan Breslau Dec 13 '10 at 12:19 Actually, great catch.

Download the latest USB Debug Kits to debug USB device drivers or …… Universal Serial Bus (USB) is an industry standard developed in the mid-1990s that defines the cables, connectors and 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. Most CPUs can access individual bytes from each memory address, but they generally cannot access larger units (16 bits, 32 bits, 64 bits and so on) without these units being "aligned" B.
