root@taygeta.dbai.tuwien.ac.at:/usr/src/sys/compile/GERALD_MADE_4.0 i386

(This is a regular kernel with USER_LDT enabled.)
>Description:
Executing /usr/bin/make as root in an NFS-mounted directory belonging
to a regular user with limited permissions (0770) causes a core dump.
>How-To-Repeat:
/sw/test is NFS mounted (v2/UDP) from a Solaris 2.6 box.

taygeta:/sw/test% mkdir x
taygeta:/sw/test% chmod 0770 x
taygeta:/sw/test% ls -la x
total 2
drwxrwx---  2 pfeifer  staff     512 Jul 17 13:08 .
drwxrwx---  8 pfeifer  operator  512 Jul 17 13:08 ..
taygeta:/sw/test% su root
taygeta# make
Segmentation fault

>Fix:
GNU make gets this right:

  taygeta# /sw/gnu/bin/gmake
  gmake: *** No targets specified and no makefile found.  Stop.
