+Summary: Assertion failure in reflection.c : line 835 (method_encode_clauses) while running Boo compiler
+
+Description of Problem:
+I've found that when compiling a certain code fragment with the Boo 
+compiler or interpreter, an internal assertion in the Mono runtime fails 
+and crashes the compiler. This can cause MonoDevelop to crash/hang if 
+compiling within the IDE.
+
+
+Steps to reproduce the problem:
+1. Fetch and untar the Boo 0.6 binary release:
+http://dist.codehaus.org/boo/distributions/boo-0.6.0.1858.tar.gz
+2. cd bin; mono booish.exe
+3. Type into the interpreter (second line should be indented, third blank; 
+chars at line start are the interpreter prompt):
+>>> try:
+...     print "foo"
+... 
+
+
+Actual Results:
+** ERROR **: file reflection.c: line 835 (method_encode_clauses): assertion 
+failed: (ex_info->handlers)
+aborting...
+Abort trap
+
+
+Expected Results:
+The runtime should not crash, and Boo should report a syntax error like 
+this:
+ERROR: Internal compiler error: Incorrect code generation for exception 
+block.
+
+
+How often does this happen? 
+Every time.
+
+
+Additional Information:
+Tested with Mono from current SVN on Ubuntu Linux (Hoary/x86) and the 1.1.8 
+packages on Mac OS X 10.4.2 and Windows XP SP2 with same results.
+
+.NET 1.1 runtime on Windows XP SP2 runs correctly.
