Subject: Freeze on FPU exception with Athlon
Date: Sat, 18 Nov 2000 02:40:19 +0100 (CET) [thread overview]
Message-ID: <20001118014019.18006.qmail@web3404.mail.yahoo.com> (raw)
The following small program (linked against glibc
2.1.3) reliably
freezes my system (Athlon Thunderbird CPU) with at
least kernels
2.4.0-test10 and 2.4.0-test11-pre5. Even the SysRq
keys do not work
after the freeze.
Older kernels (e.g. 2.3.40) seem to work. Any Ideas?
---------------------------------------
#define _GNU_SOURCE
#include <fenv.h>
#include <unistd.h>
int
main(void)
{
double a;
fesetenv(FE_NOMASK_ENV);
a = 1.0 / 0.0;
sleep(10);
return a;
}
