define it as ( __LINE__ % 10) so that the problem goes away when you add a debug statement
Decades ago I had to debug a random crash. It only happened on Wednesdays. On Wednesdays in September. On Wednesdays in September after the 10th…
I kinda want to hear more of this story... care to share the details? i.e. what was the root cause?
It was pure c code that was used to print reports, and included the date in a header. Whoever wrote it miscalculated the size of the buffer for the header by one byte. When the date was the longest month & day spelled out plus a two digit day of the month then it would overflow the buffer, resulting in the program crashing.
That's very funny.
