Hopefully this will get to the appropriate groups in IBM.  Any
suggested workarounds would be appreciated.  I normally trap ^C to
switch operating modes - don't really want the process crashing.

-- The following program illustrates a problem in the getch() routine.
-- It seems that signals are caught by getch() and not passed on to the
-- real handlers.  getch() subsequently crashes with a SYS3171 error 
-- when the next character is typed.
--
-- Demonstrating the problem:
--
-- Press any # of characters, and then attempt a <CTRL><BREAK>, a <CTRL>C,
-- a SIGTERM (via KILL), or any other condition.  The condition will not
-- be accepted - but program will halt with a SYS3171 error on next char.
--
-- Compile command: icc -W3 -Sm test.c
--
-- System: C Set/2 compiler w/ CSD's 0014, 0022 and 0028.  All failed.
--         OS/2 2.0 w/ XR06055 installed or 2.1b
