I'm getting rampant floating exceptions while running some pretty
routine calls to the math library which should generate an error,
but not core dump. The following two programs generate a FPE and
core on my system:
#include<stdio.h>
#include<math.h>
main()
{
double d;
d = pow(3.0,1000001.0);
d = pow(4.0,1000001.0);
}
or
main()
{
acos(-2.0);
}
My system is :
2.0-RELEASE FreeBSD 2.0-RELEASE #0
ldd output from one of these programs gives the following output:
% ldd a.out
a.out:
-lm.2 => /usr/lib/libm.so.2.0 (0x801a000)
-lgcc.261 => /usr/lib/libgcc.so.261.0 (0x8032000)
-lc.2 => /usr/lib/libc.so.2.0 (0x8036000)
What do I need to upgrade to fix this?
thanks, Brent
