It is possible that it cannot handle my extremely high kernel version
number of 3.14.3720150331. The value 3720150331 exceeds the length of a
signed 32-bit integer. I have never had such a problem before with
lower valued version numbers.
The error appears in a macro called DL_SYSDEP_OSCHECK inside of:
sysdeps/unix/sysv/linux/dl-osinfo.h
''int version = _dl_discover_osversion ();'', which is a signed 32-bit
value.
In sysdeps/unix/sysv/linux/dl-sysdep.c (where _dl_discover_osversion is
defined) that function it operates in an unsigned manner, however it
returns a signed value rather than an unsigned (cast to signed).
