It seems to be caused by this commit (debug-helpers.c):
I.e., the representation of C# "int[,]" has been changed from
"int" to "int[,]".
You could try to determine at compile-time which mono runtime
are you building against (use "pkg-config --modversion mono-2")
and adjust the debug helper monikers using conditional compilation.
I'd rather propose a much easier approach: Look up the method
using mono_class_get_method_from_name ().
