I have tried this simple 90-line program again recently, using MonoDevelop
3.0.2 and Mono 2.10.6, but it still fails to compile. My machine is quad-core,
and the output is now as follows:

/////////////////////////////////////////////////////////////
* Assertion at method-to-ir.c:11617, condition `load_opcode !=
OP_LOADV_MEMBASE' not met
