Hello,

I'm migrating some programs from lazarus 0.9.30 to lazarus 1.0.8 (well, actually updating and recompiling, there's no need to migrate anything). Heaptrc is showing some memory leaks in dbgrid, though it doesn't pinpoint the line exactly.
I think the leak is due to the change of type from TBookarkStr to TBookmark, and dbgrids calls GetBookmark but never calls FreeBookmark (it either discards the bookmark in local functions or assigns nil to it). I'll try calling FreeBookmark and see if the leak goes away.

Bye

Mmh, actually it does, because FKeyBoomark is assigned nil only after clearing the list of selected records.
Maybe the problem comes from the version of zeos in case it returns a different pointer for the same record?

Now I made a test project using SQLdb instead of zeos and the leak is still there.
It happens with multiselect, each new selection increases the non-freed block count.
