No log file is created for any of these cases:

$ /opt/rtems-4.6/bin/expr "xbuild_alias"
:".*[^_abcdefghijklmnopqrstuvwxyzABCDE
FGHIJKLMNOPQRSTUVWXYZ0123456789]"
/usr/bin/expr: syntax error
   : not found
   : not found
   : not found

$ /opt/rtems-4.6/bin/expr "xbuild_alias":
".*[^_abcdefghijklmnopqrstuvwxyzABCDE
FGHIJKLMNOPQRSTUVWXYZ0123456789]"
/usr/bin/expr: syntax error
   : not found
   : not found
   : not found

$ /opt/rtems-4.6/bin/expr "xbuild_alias" :
".*[^_abcdefghijklmnopqrstuvwxyzABCD
EFGHIJKLMNOPQRSTUVWXYZ0123456789]"
   : not found
   : not found
   : not found



Now, if I add a line to the script such as:
	echo "Calling expr with" "$@" >> ${HOME}/expr.log

I do get a logfile entry:
	Calling expr with xbuild_alias :
.*[^_abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789]


Can you double check and see if I made an error doing the cut-n-paste of
your script?  [attached].
