openssl problems in older netbsd-5

[Chris Ross <cross+netbsd%distal.com@localhost>]

  Hi there.  I have a [sparc64] machine running a mid-July netbsd-5  
(NetBSD 5.0_STABLE), which would make it very similar to 5.0 RELEASE.   
Slightly after, IIRC.

  I'm running pkgsrc um_imap, and I'm getting imapd core files  
regularly.  The crash seems to be in openssl, however, rather than in  
uw-imapd.  A backtrace from a core file shows:

Core was generated by `imapd'.
Program terminated with signal 10, Bus error.

  Does anyone know if there have been any changes to fix this bug in  
trunk, or in netbsd-5, inn the last few months?  Has anyone else seen  
this issue?

  Thanks.  Mostly, just looking for more information at this point...
