RE: Configure hangs at 'checking whether getcwd handles long file names properly...'

[Qingchuan Wang (qingcwan)]

Thanks for your info.
The final 'mkdir' hangs at 'wait' and I have to 'kill -9 ' to stop it.

736 [00000034d04db527] mkdir("confdir3", 0700 [wait(0x0009) = 3982] 
WIFSIGNALED,sig=SIGKILL

$ cat /proc/3982/status 
Name:   a.out
State:  D (disk sleep)
Tgid:   3982
Pid:    3982
PPid:   3978
TracerPid:      3978

If mkdir did not return, that sounds like a significant bug in your kernel or 
filer or network. I could not reproduce the problem on a system similar to 
yours (RHEL 6.10, Linux kernel 2.6.32-754.23.1.el6.x86_64, in an NFS file 
system served by a Netapp filer on a local area network).

To help you diagnose the problem, I suggest running the the attached program in 
your file system. This program is derived from the 'tar' 
configure script. I ran the program on my system and got the attached strace 
output. If you get similar output, then the bug is in how 'configure' runs its 
program somehow. If you get output where the 'mkdir' syscall hangs, you'll have 
a simple test program that you can send to your sysadmins and help them find 
the bug with their setup.

I'll CC: this to bug-gnulib since the symptoms arise in Gnulib-derived code.
