--- Comment #17 from Mikolaj Zalewski mikolaj.zalewski@gmail.com 2009-10-12 19:32:37 --- I remember I've done some more testing (however, I haven't made a patch out of that) and AFAIR the check is only in TTM_ADDTOOLW (not TTM_ADDTOOLA) and only fails on 'size > sizeof(TTTOOLINFO)' (as a side effect, the boundary value is different in comctl32 v5.82 and comctl32 v6)
