This is when a variable is set within =2Ezshrc from a back-tick command. In my search to find the actual bug I did run into kern/80130[2] since my source tree was dated one day before the fix. Argh! :) Unfortunately, it was not my bug. Here is my last post to gnu/77818: I am using 5.4-STABLE with sources from May 15th's: FreeBSD thor.farley.org 5.4-STABLE FreeBSD 5.4-STABLE #0: Sun May 15 01:46:56 CDT 2005 root@thor.farley.org:/usr/obj/usr/src/sys/THOR i386 I have a new test program[1] that I think shows the problem. My previous program actually showed another bug that has since been fixed. Actually, it shows two problems. When run within the debugger (SHELL=3D/bin/sh gdb a.out), the parent will be stuck waiting for a signal it will never receive in sigsuspend(). The other problem is that nanosleep() is exiting immediately with a return of zero (no error) although the time to sleep has not passed. To see it do this, remove the BROKEN_NANOSLEEP_WITHIN_GDB definition at the top of the program and recompile. Does anyone else see the same problems from running my test program (parent.c)? I should probably open another PR on the nanosleep(). Thank you for any help. Se=E1n P.S. David, I am unable to send you e-mails directly since there is a filter at your server that complains about having more than 4 "Received" headers in the e-mail. 1. http://www.freebsd.org/cgi/query-pr.cgi?pr=3Dgnu/77818 2. http://www.freebsd.org/cgi/query-pr.cgi?pr=3Dkern/80130 3. http://www.farley.org/freebsd/tmp/parent.c --=20 sean-freebsd@farley.org --0-116671042-1116614953=:42991--
