/usr/X11R6/lib/libXtst.so.6: undefined reference to `__fprintf_chk at GLIBC_2.3.4'

Greetings,

While compiling an application on updated FC4 I got this error:
/usr/X11R6/lib/libXtst.so.6: undefined reference to `__fprintf_chk at GLIBC_2.3.4'
/usr/X11R6/lib/libXtst.so.6: undefined reference to `__sprintf_chk at GLIBC_2.3.4'
collect2: ld returned 1 exit status

Couldn't find much about it on Google, is it because of x.org or the
application?

Thanks
