Summary: rexx abends when hostemu execio attempted

Initial Comment:
Under Win XP Pro SP3 etc, on AMD Sempron CPU, using ooRexx version: REXX-ooRexx_4.1.1(MT) 6.03 16 May 2012

Every time I try to use hostemu execio to read a disk file, the rexx interpreter crashes.

Message:
In the text exec I attached the simplest instance is an abend when trying
to read "C:\testfile.txt" using an execio command that is entirely a
literal string.  However my earlier failures used commands assembled from
various mixes of variables and literals - those are also in the test exec
but the abend happens at the simplest case which occurs at "try(0)".

Something else very strange happens too...  I have another exec which runs
every minute whose purpose is to find DrWatson log & dmp files (in the
standard place) and move them elsewhere with a time-of-move timestamp in
their names.  This has been running fine for months.  Now, when I have DrW
files created by the test exec here abending, the exec that runs soon after
that abend sees the newly created DrW files, moves them ok, goes through my
standard terminating code (which nearly all my execs have) and writes lines
to a log and stops.  Except... the rexxhide.exe under which the
file-mover-exec was running keeps on running.  I've had to force it out of
the system by using "end process" in task manager.

When I first saw this the test exec (ie the one that abends) was also
running under rexxhide.exe, but I've also seen rexxhide.exe 'stall' when
running the file-mover-exec when the abending exec ran under rexx.exe or
rexxpaws.exe.    


I have another exec which uses WMI to list the processes for any
rexx-related task (written when I was previously investigating multiple
rxapi tasks).  This shows, typically, something like:

Win32 processes running rexx.exe or rexxhide.exe or rexxpaws.exe or
rxapi.exe:
