Oleg,

I'm adding this back in to the list.

My hardware is a 200mhz Pentium MMX running Slackware 4.0 with kernel
2.2.6.  dmesg reports "Intel Pentium with F0 0F bug - workaround
enabled."  I'm not sure that is relevant.  I tried several gcc
switches (-mno-486, -mno-fp-ret-in-387, -msoft-float) which didn't
work.  When I added the -O2 switch to gcc and ran a.out under gdb
I got:

Program received signal SIGSEGV, Segmentation fault.
0x40060607 in ldiv () from /lib/libc.so.5

What did work was booting Slackware 7.1 which uses egcs-2.91.66.
So there must be a problem with Slackware 4.0's libc5?  I realize
it is time to switch to more recent software.

Thanks Oleg,
