This crashes at runtime because of a stack overflow, without stack frame or error message (DMD 2.053), no stack trace, or line number are shown:
int foo(int n) { return n ? foo(n - 1) : 1; } void main() { foo(100_000); } If you aren't running a debugger then receiving a nude crash is not so nice, because in a larger program there are many functions that may be the cause of such stack overflow. So is it possible to add some stack protection code (in non-release mode only, if necessary) to receive a stack trace in this case? Bye, bearophile
