I have found difficulties to run RTEMS shell
on latest 4.11 as well. The POSIX keys implementation
is used for task specific variables. May it be that
even if POSIX support is disabled, the 
CONFIGURE_MAXIMUM_POSIX_KEYS
CONFIGURE_MAXIMUM_POSIX_KEY_VALUE_PAIRS
has to be setup. And for sure, when POSIX is enabled
in RTEMS build (our case), the at least one key-value
pair has to be allocated for each shell instance.

There are our application template
  http://rtime.felk.cvut.cz/gitweb/rtems-devel.git/tree/HEAD:/rtems-omk-template
changes for latest RTEMS 4.11 git.

Best wishes,

              Pavel
