Well, now it doesn't assert crash, but (on the Solaris 8 machine):

after (I think - I was picking messages at "random"),

. SELECT test.gz (ok)
. FETCH 1:167 FULL (ok)
. FETCH 167 BODY[] (ok)
. FETCH 123 BODY[]
* 123 FETCH (BODY[] {1769} (ok)
. FETCH 39 BODY[]
* 39 FETCH (BODY[] {1671}
Connection closed by foreign host.

I'd deleted the index files to be sure it wasn't left over from the 
previous problems.

I'll try on the SuSE box as well.

Best Wishes,
Chris
