You're right, so I modified to use asprintf(3) to handle the indeterminate
buffer size.
And there would be exit the process if overflow.

Change to escape code is OK. But note that escape codes
are terminal-specific, code which wants to work on wide
variety of terminals would use terminfo or ncurses.

Actually the message "Semantic Errors" occurs 35 times during a normal
successful build of FriCAS. Many but not all of these are due to
something being "BOTH a variable and a literal". Clearly these are not
really "errors". At most this might be just a helpful warning but I
cannot see any

Many graphs in chapter seven FriCAS UG do NOT correspond to what announced in
the text (I was preparing a list of patches but you anticipated me).
In 2D graphs this is due to a missing 'title=...' in the invoked command draw
and also due the fact that 'unit=...' shows nothing

Yes. No problem. Maybe I should add
vp := draw(sin(11*x),x = 0..2*%pi,title == "Large and unit",
unit==[0.2,0.2])
I already had answered this question directly:
works for me perfect:
you must make sure that in the control panel you have "units on" and you
possibly have to scale the size of the window in order to have space for
tick labelling.

Hello everyone,
Fixed magic number and buffer overflow in 'start_user_buffer'.
Bests,
