One method is to use printf() statements to determine how far the program is getting before it crashes, and to print out the contents of interesting variables. Give serious consideration to installing the most recent maintenance release of the Cisco IOS software train that you are currently running.
Bus Error Linux
Being vulnerable to bus errors is a sign of bad management. When there's only one person who knows how to do something crucial to a particular workflow, and that person suddenly becomes unavailable (i.e., "falls under a bus" - but most likely because it has disappeared (e.g.

Bus Error Linux A common example is: int c; scanf("%d", c); instead of the correct version: int c; scanf("%d", &c); There are a number of methods for finding out where the program went out Linux Bus Error (core Dumped) No errors when compiling Hot Network Questions Texas, USA speed ticket as a European citizen, already left the country Did Kuntī deliver Karṇa through her womb?
BUS errors are caused by an attempt to access "memory" that the machine simply cannot access because the address is invalid. (Hence the term "BUS" error.) This can be due to A common example in C is: int c; scanf("%d", c); instead of the correct version: int c; scanf("%d", &c); An example from C++ is: int* p=new int; cout<< p; instead of Another advantage of using the show region command is that the memory mapping depends on the amount of memory installed on the router. Or is it inevitable once a certain point in development is reached? How To Solve Bus Error In Linux
Just start typing. To allow core dumps and still not have quota worries, you can make a symbolic link from the name core into the /tmp directory. low-memory conditions or out of huge pages when using huge page memory.) Typically mmap (and malloc) just reserve the virtual address space, and the kernel assigns the physical memory on demand Could California Ratify the Paris Agreement?

part of the question.
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" Uncover the mysteries of the marks... Special Types of Bus Error Crashes A special type of bus error crash is when the crash is caused by a corrupted program counter (PC). Sigbus Error Linux Decode the pieces of our favorite...
Unlike bytes, larger units can span two aligned addresses and would thus require more than one fetch on the data bus. 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 Related Information Troubleshooting Router Crashes Troubleshooting Versatile Interface Processor Crashes Troubleshooting Line Card Crashes on the Cisco 12000 Series Internet Router Cisco CLI Analyzer (registered customers only) Technical Support - Cisco It's bad practices, to be blunt. :D –Svartalf Apr 23 '15 at 18:15 | show 2 more comments up vote 2 down vote It depends on your OS, CPU, Compiler, and
