No, Daniel. When we just create TDecompressionStream we seeks to 
soFromBeginning, 0. We have raw_read = 0, so offset = 0 too after 
dec(offset, raw_read). And next condition with offset < 0 then is false 
=> so no reset call.

I fixed that locally after your commit and lazarus works.

Best regards,
