One of the developers of Asterisk told me it is cause by -fstack-protector. This indeed shows up during the compilation of the zaptel kernel modules.
A sugesstion was to turn off -fstack-protector. Anyone have a hint how I do that in e.g. the rpm spec file?
One way is to add "-fno-stack-protector" to the compiler flags (e.g., %{optflags} or $RPM_OPT_FLAGS for rpm's building tools).
Of course, another (probably more secure) way is to patch the code so that it works with the stack-protector. :-P
