There is also some weird problem, that prevents loading bzip2-compressed modules when loader(8) compiled with Forth support. Instead of understandable `out of memory' error loader completely loses control after starting loading any bzip2-compressed file (I'm suspecting stack overwriting, but not sure how to debug this). Things are OK when it compiled without Forth, though. -Maxim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
