Product: Mono: Runtime

OS/Version: FreeBSD

Code Example
For a recursive call to a class property (please refer to the line "CrashValue
= value" in the code example), Windows .NET runtime throws a
StackOverflowException as expected. However, the Mono runtime on Linux and
FreeBSD (I expect to found it among various operating systems) would crash with
"Bus error: 10 (core dumped)" (or Segmentation Fault on Linux). This error
reflects that the StackOverflowException for recursive class property call is
not handled properly in Mono.
Here are the system environment tested (the attached code.cs crashed on all the
testing environments)
