C Free Bus Error


I suspect it might have to do with memory or overflowing the buffer, but that's completely unscientific and a gut feeling.

I get the feeling that you are actually running your program, that the error is seperate from the compilation process, and that it stems from you not checking the return values 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 Will it cause mis-alignment errors on a fragile architecture.

  • Like SIGSEGV, this signal is typically the result of dereferencing an uninitialized pointer.

Macro: int SIGEMT Emulator trap; this results from certain unimplemented instructions which might be emulated in software, or the operating system’s failure to properly emulate them. For instance: unsigned char data[6]; (unsigned int *) (data + 2) = 0xdeadf00d; This snippet tries to write the 32-bit integer value 0xdeadf00d to an address that is (most likely) not Although the name is derived from “floating-point exception”, this signal actually covers all arithmetic errors, including division by zero and overflow.

I wasnt thinking right. In particular, SIGBUS signals often result from dereferencing a misaligned pointer, such as referring to a four-word integer at an address not divisible by four. (Each kind of computer has its I also used the following link to figure out how to copy a string to an array: stackoverflow.com/questions/1088622/… –GeekyOmega Jul 30 '12 at 19:44 I have to admit, this I feel this may indeed be a better solution. –GeekyOmega Jul 30 '12 at 19:45 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign

In various fields of research (perhaps wider), the slang "bus error" has a different meaning, which I think could be a relevant answer. Sigbus Error Linux The problem with this is that array[x] doesn't belong to the array, the array only has useable indices of 0 to (x - 1). The goal in my game is to take a huge 5049 x 1 text file of words.

It is just as catastrophic as a "real" bus error, since without this person's knowledge of how to maintain or even execute the research workflow, the entire system falls apart.

A 17th century colloquial term for children, in the way we use 'kids' today Higher up doesn't carry around their security badge and asks others to let them in. There are two problems with that: you are overwriting the value everytime a new string is read and the buffer is in the stack, and is invalid once the function returns. Is there some reason trying to free up the memory is causing a crash? Bus Error Core Dumped C Programming So, it is aligned.

The IEEE Standard for Binary Floating-Point Arithmetic (ANSI/IEEE Std 754-1985 and ANSI/IEEE Std 854-1987) defines various floating-point exceptions and requires conforming computer systems to report their occurrences. It does not create the LMC.o file at all... The mmap spec says that: References within the address range starting at pa and continuing for len bytes to whole pages following the end of an object shall result in delivery POSIX describes SIGBUS as: Access to an undefined portion of a memory object.
