[mod.computers.ridge] Cmd Line bug in Rx Compilers

dcass@NRTC.ARPA.UUCP (05/18/86)

I noticed a nasty little difference (Bug!) between the Rx compilers
(RC, RP and RF) and normal UNIX compilers (CC, F77, PASC).  When you
use the -o [load output file] switch, the compiler does not check
to see if the file already exists, and is not executable.  As such, if
you, by mistake mind you, type:

	rc -o test.c

The rc compiler will happily erase test.c, then complain that no input
file was specified.

THIS IS AN INSIDIOUS BUG, esp. in an operating system without UNDELETE.
