grep, ln both segfault


RH8 server I can't explain what causes it. grep, ln, and possibly others exit immediately with a segfault, even with no arguments or the --help argument. I can't think of anything particular that I changed on the machine.


I already tried reinstalling grep from the RPM, and it worked for a few moments, then stopped working. gdb was no help, it didn't make any sense at all. I have no idea how to read an strace, but I included it here if it'll help.

Have you perhaps updated glibc sometime recently? Just so you know, grep typically links against linux-gate.so.1, libc.so.6, and /lib/ld-linux.so.2.
