thank you ...
I added some librarys as you like suggest.
I recompiled BusyBox with:
USE_SYSTEM_PWD_GRP = true
The WARNING is fixed but signal 11 is still present :(

I use DirectFB library for build graphic interface under frame buffer.
On RedHat_7.3 I compile my source both for X11 that FB (with two entry on
Makefile).
On Busybox (with the same kernel :(  my application crash in this way:
~ # ./lissajouls

Can you (or anyone) help me ?
Thanks very much in advance!
