Are you on a platform without VFP? If so, we need to build with a different set of nanojit flags -- no NJ_ARM_VFP, and NJ_SOFTFLOAT. That path is somewhat less tested, but should be ok. I have some work in progress to make this runtime selectable, though actually detecting if VFP is present is rocket science.

Here's a quick test, just compiled straight with cl with QRfpe- . It uses VFP to do some math, and then puts up a messagebox saying OK if it succeeded... check if this works?

This should be fixed by detecting the supported instruction set features at runtime, in bug 480796.
Depends on: 480796
