#10 debugger crash

[Detlev Hartenstein]

I was using the ficl.exe for windows which is a part of
the ficl 4.0.31 distribution.
i defined the word stars:
ok> : stars 0 do 42 emit loop ;

Then I tried to debug it:

ok> 10 debug stars

the output is:

: stars
0 0 (instruction 17)
1 do (leave 8)
3 literal 42 (0x2a)
5 emit
6 loop (branch 3)
;
S: [1] 10
next: 0 (instruction 17)
dbg> ok>

Then I entered i and ficl crashed (Windows shows a
crash message box).
It worked the same way while entering o.
What is wrong?

Thanks for help!
Detlev

This is the same operation under Mac OS X 10.3.4

ok> : stars 0 ?do 42 emit loop cr ;
ok> 18 stars
