+Summary: Runtime cannot find method (multiple generic parameter constraints)
+
+Description of Problem:
+
+The program below compiles correctly with Mono gmcs and Microsoft csc, but
+the Mono 1.1.12.1 runtime for Debian Linux cannot execute the resulting exe.
+
+Steps to reproduce the problem:
+1. Compile with gmcs or csc
+2. Try to run it with mono
+3. Observe segmentation fault
+
+Actual Results:
+
+** (Bug19.exe:11783): WARNING **: Missing method CompareTo in assembly
+/usr/local/mono-1.1.12.1/lib/mono/2.0/mscorlib.dll token 6000046
+
+=================================================================
+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.

+
+Additional Information:
+
+The gmcs-generated exe runs fine on Microsoft .Net SDK 2005 final release.
+
+The mono runtime crashes also on the csc-generated exe.
