Hi Paolo,
I don't have a solution but I've noticed the same thing. I've been
sending commands from Python to IDL by launching IDL as a child
process within Python (using Pexpect). I've found limits of 1024
bytes for sending a single line, but 2048 bytes if I split the line up
and send it in pieces (like pasting twice). However, using IDL from
the shell this happens:
[IDL 6.4]
IDL> x='aaaaaaaaaaaaaaaa ... aaaa [keep typing/pasting until it
refuses further input]
IDL> print,strlen(x)
4092
IDL> exit
% Internal error: buffer overrun in IDL_SFilePrintf() detected.
The paste limit seems to depend on the shell/terminal - e.g., using
Terminal on the Mac and ssh-ing into a Linux machine, I'm able to
paste the x='... command in full (4095 bytes). But using IDL on the
Mac it complains after slightly more than 1024 bytes.
But, as you say, the problem is peculiar to IDL, not the shell/
terminal in general.
