# This test checks whether the Solaris kernel can directly execute compiled
# shell code.
#
# This was reported as CR #6862121 ("shbinexec kernel module defunct"):
# ------------ snip ------------
# [Originally reported by Sun Japan]
# The new shbinexec kernel module added in B106 is defunct, originally
# caused by my mismerge of the original development tree and later
# because the matching test module didn't test it correctly (April
# quickly discovered the problem but the issue drowned in the cleanup
# putbacks ).
# Frequency
# Always
# Regression
# No
# Steps to Reproduce
# $ cat test1.sh
# print hello
# printf "args=%s\n" "$@"
# $ shcomp test1.sh test1
# # note: this MUST be bash since ksh93 has special support for compiled shell
# # scripts which causes the kernel module to be bypassed (that's why the tes
# # never worked)
# $ bash -c './test1 "a b" "c" "d"'
# Expected Result
# hello
# args=a a1
# args=b
# args=c
# Actual Result
# ./test1: line 1: a: not found
# Error Message(s)
# ./test1: line 1: a: not found
# Test Case
# See above.
