[net.unix-wizards] C bug logs?

peterr (11/22/82)

Has anyone out there kept logs of bugs encountered while developing systems
using C?  There's apparently a Bell-only system for logging bugs reported
by people in the field, but I'm more interested in the mistakes the original
programmer makes (or, to put it operationally, in the changes to the source
made between successive invocations of cc).  I'll summarize replies.
