[vbox-dev] movzx error compiling on Mac OS X

[Frank Mehnert]

Kyle,

I'm not sure which instruction is causing this error message. Please could
you:

 touch src/VBox/Runtime/req.cpp
 cd src/VBox/Runtime/req.cpp
 kmk KBUILD_VERBOSE=2
 cut'n'paste the g++ command line but replace -c by -S and the output
   file name .../req.o by req.S

then perform the command, look at line 829 and post the instruction on
that position.

Thx,

Frank
