Also, if this isn't stock code, have you made any changes that could alter any of db.c, oasis, olc, or the .wld files. (Which, at least according to my version of stock bpl21 you have, since line 2272 is in store_to_char, unless there's some oddness from compiler optimization I'm not thinking of atm.) <blind guess> You're trying to read a string bigger than the local buf or tmp is created to hold. </blind guess> -me -- +---------------------------------------------------------------+ | FAQ: http://qsilver.queensu.ca/~fletchra/Circle/list-faq.html | | Archives: http://post.queensu.ca/listserv/wwwarch/circle.html | | Newbie List: http://groups.yahoo.com/group/circle-newbies/ | +---------------------------------------------------------------+
