Hi, I have a port for Mono's XSP web server for ASP.NET but it has never worked from 1.0 to the latest version, 1.0.6. The crash has always been the same. Finally I've had a chance to sit down with a machine and generate a usable backtrace. The attached backtrace was generated on -STABLE from February 19 using Mono 1.1.4 after connecting to the server with a browser. (Mono 1.1.4 does not build on -CURRENT right now which has become the version I'm focusing on for crashes since 1.2 will be out in late April. The crash does occur on Mono 1.0.6 as well which is in ports and does build on -CURRENT.) If needed, I can regenerate the backtrace using -CURRENT once 1.1.4 builds. The xsp and mono-devel ports can be found here: http://tmclaugh.freeshell.org/files/mono/ Thanks, Tom Backtrace: [tom@europe-monodev test]$ cd /usr/local/share/doc/xsp/test [tom@europe-monodev test]$ gdb /usr/local/bin/mono GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
