V3507. AUTOSAR. The macro with the 'setjmp' name and the function with the 'longjmp' name should not be used.

March 3, 2021

This diagnostic rule is based on the software development guidelines developed by AUTOSAR (AUTomotive Open System ARchitecture).

The analyzer issues the warning when it detects the 'setjmp' or 'longjmp' names because misusing them may result in undefined behavior.

Here is an example of code triggering this warning:

jmp_buf j_buf;
void foo()
{
  setjmp(j_buf);
}
int main()
{
  foo();
  longjmp(j_buf, 0);
  return 0;
}

The 'longjmp' function is called after the function calling 'setjmp' returns. The result is undefined.

This diagnostic is classified as:

  • AUTOSAR-M17.0.5
