I discovered that if I substituted juan db 0x45 for juan db 0x44,0x33,0x22,0x11 then (gdb) print juan did not produce any error. Cannot Access Memory At Address Gdb Core So one can't count on an array out of bounds to always result in a segmentation fault. Finally, depending on the compiler and how it is called in the default environment, a program may not stop and issue a SIGFPE after doing something non-sensical. I can take another screenshot if necessary.

Using a debugger greatly helps in identifying these sorts of problems. http://kelcours.com/cannot-access/gdb-core-file-cannot-access-memory.html It was starting in the initialization code then it went to another function that wasn't even call at the time. The output from the job can also indicate a problem with the state of the program or a lack of progress. When you hit a breakpoint, the debugger is reading the registers.

One should also disable all processor optimzations, by specifying the -O0 flag (or equivalent), otherwise compiler optimizations may lead to misleading debugger behavior or obscure the bug (this is not the warning: Could not find object file "/private/tmp/boost-js1W/boost_1_54_0/bin.v2/libs/thread/build/darwin-4.2.1/release/threading-multi/pthread/thread.o" - no debug information available for "thread.cpp". One can also look at a stack trace, to see what has been called up till this point: (gdb) where #0 0x0000000000400f81 in divide (d=0, e=1) at /home/sndemo/bugs/bugs.f90:19 #1 0x0000000000400edd in Cannot Access Memory At Address 0xffffffff These examples are trivial, and are simply intended to show how easy it is to use the debugger.

Your .map file shows that you have a lot of space free- you are only using about 1087 bytes of your 32K of RAM (LPC17xx family part) so the rest is check over here Registration is quick, simple and absolutely free.

When I type x/xw 0x208c it gives me back error which says Cannot access memory at address 0x208c. Last edited by stf92; 07-11-2011 at 10:15 AM. One may then run the gdb where command to get the stack backtrace, etc., to further identify the problem.
To debug parallel programs users should consult the SHARCNET Parallel Debugging with DDT tutorial. So, in particular, I needn't care about the DS segment register.

They automatically allow programs to stop when they encounter an FPE. I rewrote that function and the error disappear. Type "show warranty" for details. How to react?
