(yes, those are 1GB stacks! Do not seem to influence these results)

The errors are NOT due to the changes in stack checking: attaching 'make test' output for both HEAD and 8.5b2 (before the stack check changes) in a build with
  --disable-shared --enable-symbols --enable-threads
The two are not the same but similar, there are a few more segfaults in HEAD.

Note that juliannoble reports no problems with 'make test' in #1860425

This Tracker item was closed automatically by the system. It was
previously set to a Pending status, and the original submitter
did not respond within 14 days (the time period specified by
the administrator of this Tracker).

This does not repro on core-8-5-branch either.  Tested with and without --disable-shared.

mistachkin, can you check the core-8-5-branch?
If you cannot repro there either, we should close this?

This bug does not repro on HEAD on my machine.

Found an old slow 4.9 system to try it on. 
This system does get the segmentation violations etc.

I don't have a FreeBSD 4.x system to build on - but tests run ok on 6.2
Just fetched cvs head and configured with --disable-shared --enable-symbols --enable-threads

Adding ERR.NOCHECK for a build with -DTCL_NO_STACK_CHECK, illustrating that the issues are not (only?) due to stack checking.
