Tcl

"lsearch" crashes under certain circumstances:

Condition 1:
The list and the query object share the same Tcl_Obj.

Condition 2:
Options used for lsearch are "-exact" and "-integer" or "-real"

crash example1:
set x 0
set y $x
lsearch -exact -integer $x $y


crash example2:
set x 0.2
set y $x
lsearch -exact -real $x $y

does not crash (example1 without -exact):
set x 0
set y $x
lsearch -integer $x $y

I tested this with tcl8.5b3 (windows) and tcl8.5b1 (linux)
