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.

Ran XOscillo.exe from Windows XP sp3 machine and received an Application Error 
message window saying "The application failed to initialize properly 
(0xc0000135). Click OK to terminate the application.

Woops! .NET v3.5 was not installed. Get a blank screen now, but need to connect 
a signal to the Arduino.

Downloaded Arduino software from Arduino web site which included the USB serial 
port driver. Compiling samples and uploading from XP is working. Running 
XOscillo from Windows XP shows waiting for trigger.

Still cannot run XOcillo from Raspberry Pi Linux, see original posting with 
errors.

Looks like the issue is with floating point support in mono for Raspberry Pi 
being an armv6.
