Package: libmono0 Version: 1.9.1+dfsg-1 Severity: important Tags: patch
Mono 1.9.1 appears to contain a runtime bug which may cause crashes - one
repeatable example is compiling XSP, which fails in the same place on many (but
not all) AMD64 systems running Debian Sid or Ubuntu Intrepid:
/usr/bin/mcs -r:System.Web.dll -t:library -out:codebehind1.dll
codebehind1.cs
