Re: My favourite timing bug
Back in the 70's, I helped write a signal processing system on a little-known "high speed" (10 MHz) box. When our big pile of Assembler seemed to be bug-free, we removed the debugger, and the drum code promptly malfunctioned. (For the young: a drum is a head-per-track disk.) It turned out that commands to the drum controller were not interlocked: if you issued a command "too soon" after the previous command, bad things happened. And of course removing the debugger made the software faster.
