In this case, I suspect this will fail if the libc is not compiled as a part
of eCos. In another message you mentionned the fact that eCos was not
written with dynamic allocation in mind so I wonder how it handle a
"dynamic" new operator. Does/Can it uses memory pools?

The one I had to apply when building the gnu toolchain for eCos (as refered
in the eCos installation documentation)
