FreeBSD 10.0-RELEASE FreeBSD 10.0-RELEASE #0 r260789: Fri Jan 17 01:46:25 UTC 2014 root@snap.freebsd.org:/usr/obj/usr/src/sys/GENERIC i386
>Description:
In the 10.0-RELEASE, the IL library (from the "devil" package), when linked to any program, such as ``int main(void) { }'', causes the program to segfault before main() is entered. The backtrace is:
0x00000000 in ?? ()
(gdb) bt
#0 0x00000000 in ?? ()
#1 0x28769ec4 in __dynamic_cast (src_ptr=0x287a1180, src_type=0x2879bf2c,

>How-To-Repeat:
% cat nop.c
int main(void) { }
% gcc46 -g nop.c -L /usr/local/lib -lIL -o nop
% ./nop
Segmentation fault (core dumped)
(Clang can also be used.)
