Yes, I arrive to this point only because we have a problem in wxWindows:
We have a project where we build:
-- X (tiny) (cross compiled)
-- glib (compiled native)
-- gtk  (compiled native)
-- wxGTK (cross compiled)
-- minimal sample (wx-based)
for ppc system (ELDK 2.1) & x86 all works fine

On ELDK 3.0 (recompiling all as above) all works (X and gtk tests)  but not
wxGTK (also with wx samples) and because this is the only package build in
cpp this is why I was think to the cpp compiling.
In effect the test below is broken, written whit the [] runs.

So the question change: does anybody try to compile and use wxGTK with
ELDK3.0 ??

Lost the beer, the code is wrong but the segfaulted is in the "new"
(checked with a printf before the memset & also with gdb eh eh)
