myisamchk segfaults on spatial index

[Jean-Paul Le Fèvre]

Hi,
I'm currently working with mysql 5.0.4. I've a table with a geometry column (type point).
Since my table can be pretty big (nbr of rows > 20 millions) I've added a spatial index.

If I try to compress the table with myisampack I'm unable to rebuild the index with
myisamchk ( -r or -o) : it immediatly crashes with a Segmentation fault.

Before mass insertion I've tried to run myisamchk --keys-used=0 but once the insertion done
myisamchk segfaults when I want to recreate the index.

Index on other columns seem to be correctly handled my myisamchk.

Is there anything to do ?
