[ubuntu-mono] [Bug 240671] [NEW] Mono 1.9.1 crashes with native stacktrace whilst compiling XSP on AMD64

[directhex]

Public bug reported:

Binary package hint: mono

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

      =================================================================
      Got a SIGSEGV while executing native code. This usually indicates
      a fatal error in the mono runtime or one of the native libraries
      used by your application.
