try-error in batch and interactive mode (PR#1934)
I have a tiny R script performing two tasks, the first one of which may
contain error.
mammon(12)% cat z.R
version
options(show.error.messages = FALSE)
try(b <- log("foo")) ## task 1
1 + 2 ## task 2
Running in batch mode from a solaries machine, the second task never got
started; see below:
mammon(13)% R BATCH --vanilla -q z.R
mammon(14)% cat z.Rout> invisible(options(echo = TRUE))
> version
_

arch sparc

The second task does start if run on a linux machine.

The same code works well if pasted into an interactive R window on both
system, of course.

Note that R --restore --save --no-readline --gui=none -q < z.R > z.Rout works for me (in tcsh or sh). That should give you a workaround.

try-error in batch and interactive mode (PR#1934)
This is caused by the call to fflush(stdin) in Rstd_FlushConsole() in src/unix/sys-std.c. I've commented on that before: fflush on an input stream is not defined on the Solaris help page, and it appears to flush piped input. I've removed the call. If anyone knows what it was intended to accomplish, please find another way to do it.
