Why= = blame on xchat if it works perfect with Perl built with = WITHOUT_PERL_MALLOC? Maybe it's me that I don't understand. ;-) Because,= = if Perl has its own malloc then why would it gets mix up with jemalloc? > I seem to have a rather vague recollection that something similar has > happened with xchat before (some years ago). > > One more possibility is that xchat is threaded and Perl is not. I doubt it, because it works in FreeBSD 6.x and WITHOUT_PERL_MALLOC in = FreeBSD 7.x.
