Details:

When running in terminal (--no-gui), attempting to define a string variable,
e.g. s = 'x' but instead of x using a long string (~25K, copy & pasted from a
log file), Octave crashes with the error:

error: input buffer overflow, can't enlarge buffer because scanner uses
REJECT
input buffer overflow, can't enlarge buffer because scanner uses REJECT
*** Error in
`/usr/lib/x86_64-linux-gnu/octave/4.0.0/exec/x86_64-pc-linux-gnu/octave-gui':
corrupted double-linked list: 0x00007faa78122b30 ***


I've attached a file containing the text - copy & paste it into terminal to
recreate the crash.

It should at the very least give a proper error message (input string too
long) without crashing. But even better would be to support longer strings
