[Bug] VICE 1.17 crashes after approx. 72 minutes run

The information in this article applies to the following versions of VICE:

version 1.17 on all plattforms

PROBLEMEXPOSITION

CAUSE

There is a problem in riotcore.c which resultis in an uninitialized variable. This variable causes a division by zero on timer overflow.

SOLUTION

This is fixed with version 1.18

STATUS

The VICE team has confirmed this to be a problem in the VICE versions listed at the beginning of this article. It has been corrected in all subsequent versions
