logfile with -ldebug

Hi,

I succesfully compiled the orocos_toolchain_ros (without orogen support) based
on RTT and OCL 2.3.x on Mac OSX 10.6.6. After some fiddling with the
DYLD_LIBRARY_PATH I can succesfully start the deployer, rttlua and the ros
integration stuff. All working fine but:

the conversions between types does not work which in the case of rttlua causes
a segfault (backtrace below) and in the case of the deployer failures (the
logfile is attached):

var double a
23.165 [ Debug ][Logger] Building variable 'a' of type float64
= 0

Deployer [S]> a=1
Fatal Semantic error: Incompatible types. Cannot assign: float64 = int32.
Deployer [S]> a=(float64)1
34.525 [ Debug ][Logger] Building variable 'constructor' of type float64
= 0

Deployer [S]> a=1.0
Fatal Semantic error: Incompatible types. Cannot assign: float64 = float64.

The backtrace for rttlua:

Program received signal EXC_BAD_ACCESS, Could not access memory.
