Hi,
I've a probelm using the signal function.
I'm using Kernel 2.4.4 from Denx. When I install a signalhandler for SIGCHLD, I
get an segmentation fault, when the child process is finished.
I've found out that this happens, when the function installed by signal returns.
Any ideas?
regards
Martin"

You probably have a problem with your cross tools / libraries /
header files.

Bad cross tools, header files, and/or libraries...
Works here...

Any technology distinguishable from magic is insufficiently advanced.
