Shep, if you use
sendbug(1) to report your bug, a structured problem report is sent to gnats@, which is the problem reporting database tracking tool program, and that
will assign a PR number if it receives a formatted report. The bugs@ mailing list is sent a copy, and followup discussions may inadvertently occur there, but it is not used for reporting bugs directly.
If you just post to bugs@, your report will not be assigned a number, and will likely get lost in the noise.
That said, having a PR number is not a guarantee of immediate attention.

Edited to add: I've just looked at bugs@ and see what I think are your two posts there, on March 8 and again on April 19. They did
not go through sendbug, so may not be seen by the appropriate developer(s).
