Sorry to hear that.

set hits [concat $hits [mk::select $v -first 2 -glob $i $s]]

mk::select $v -first 2 -glob $proplist $s
Well, when swapping the rows, this script crashes with seg fault.
I had a look at the row contents and the search results - all is
fine, but
after the second or third iteration over nr it always crashes :-/
What I'm doing wrong? Have I misunderstood the mk::cursor command or
their use?
Make sure you use Mk4tcl 2.4.9.3 - from the change log:
2004-01-22 Fixed refcount problem with temp rows in Mk4tcl
This was a long-standing bug: "mk::row create" did not work right
because the tracking of temporary rows was completely messed up.
Added test case for Tcl (mk6.8), fixes FB14, BTS#78, and BTS#29.
It really drives me to despair cause it's not the first seg fault
with mk4tcl
- isn't it possible to use property names with blanks?
I'm not sure. I always avoid blanks in property names. Tcl has no
restrictions, but identifiers in C++ and Python are limited in the
same way.
Christoph (frustrated) :-(
Ouch.
