Hi, i m trying to update my development server (VM) by making a clean installation from git master, 
but i m getting a core dump while compiling:

/bin/sh: line 1:  9386 Segmentation fault      (core dumped) ./make_modem_filter -m V.17 -i -r > v17_v32bis_rx_fixed_rrc.h
make[7]: *** [v17_v32bis_rx_fixed_rrc.h] Error 139
make[6]: *** [all] Error 2
make[5]: *** [all-recursive] Error 1
make[4]: *** [/home/fs/freeswitch/libs/spandsp/src/libspandsp.la] Error 2
make[3]: *** [mod_spandsp-all] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2


i followed the classic steps (bootstrap,configure and make) is anyone experimenting the same issues ???
my info is:
Linux pbxvm 3.1.5-1-ARCH #1 SMP PREEMPT Sun Dec 11 06:26:14 UTC 2011 i686 Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz GenuineIntel GNU/Linux

thanks!
