Hmmm... I really need some holidays... I couldn't manage to find the
commit today (too tired?) and now I remember grep is my friend
$ git checkout mdb.master
$ git log --pretty=oneline | grep 8336
58d1fd4c73c96ef3097816e975b3d421ead4d86e ITS#8336 fix page_search_root
assert on FreeDB
I'll have a look tomorrow. Thanks. Regards,
Jephté
