BIRD 2.0.4 segfaulting on ARM

[lorenz at irmhil.de]

Hello,

after a "make clean", "./configure" and "make" I got this compile-time
warning:

--- snip ---

sysdep/unix/io.c: In function ‘times_init’:
sysdep/unix/io.c:135:45: warning: comparison is always false due to limited range of data type [-Wtype-limits]
   if ((ts.tv_sec < 0) || (((s64) ts.tv_sec) > ((s64) 1 << 40)))
                                             ^

But unfortunately the segmentation fault is still there. Is there
anything I can do?
