SVN rev. 1715 on Mac with double precision is broken..?

[ola]

Hi,

I just installed Bullet from SVN on a new mac, and built it in double-precision mode. It seems that the collision detection is not working at all. For example, shooting boxes in any demo makes them just fly through everything.

Single-precision mode works just fine, by the way.

I compared by building the same version on Linux, there it's all OK in both single and double-precision mode.

In the SVN log, at r1711, it says that SIMD has been enabled for OSX Intel, so maybe this is the reason? I am guessing SIMD won't work in the double precision mode, but maybe is still being used.

Best regards,
Ola

Good point, the SSE implementation assumes single precision indeed.
Can you try out revision 1716?

Thanks again for the report,
Erwin
