If it is not in the man pages or the how-to's this is the place! Program terminated with signal SIGFPE, . Jan 13,  · Even though SIGFPE stands for “Signal: Floating Point Exception,” this signal is generated on pretty much any arithmetic exception (floating point or integer). Don’t expect to be able to catch stack overflows. Often the signal handlers are invoked Author: Job Vranish. In addition to the problem stated by Shafik, fibonacci(0) and fibonacci(1) will fail because the assumption that it's okay to leave c in int fibonacci(int) uninitialized since it's being set in the loop is a bad one for n = 0 and n = 1 since the while loop will be skipped and thus you will be returning an uninitialized variable.

Java For Android Tutorial #8: Arithmetic Exception / by zero, time: 2:15

I have a C++ application cross-compiled for Linux running on an ARM CortexA9 processor which is crashing with a SIGFPE/Arithmetic exception. Initially I thought that it's because of some optimizations introduced by the -O3 flag of gcc but then I built it in debug mode and it still crashes.. I debugged the application with gdb which catches the exception but unfortunately the operation. SIGFPE The SIGFPE signal is sent to a process when it executes an erroneous arithmetic operation, such as division by zero (the name "FPE", standing for floating-point exception, is a misnomer as the signal covers integer-arithmetic errors as well). SIGHUP The SIGHUP signal is sent to a process when its controlling terminal is closed.

I am trying to build a simple C program for two different Linux environments. On one device the program runs fine, on the other device the program generates a floating point exception. Floating point exception (SIGFPE) on 'int main(){ return(0); }' Ask Question . The operation triggers SIGFPE: SIG is a common prefix for signal names; FPE is an acronym for floating-point exception. Although SIGFPE does not necessarily involve floating-point arithmetic, there is no way to change its name without breaking backward compatibility. GDB is a bit clearer about this and calls it "Arithmetic exception". On Linux you can use the GNU extension feenableexcept (hidden right at the bottom of that page) to turn on trapping on floating point exceptions - if you do this then you'll receive the signal SIGFPE when an exception occurs which you can then catch in your debugger. Watch out though as sometimes the signal gets thrown on the floating point instruction after the one that's actually causing the.
