Follow-up Comment #30, bug #46466 (project octave):

I ran plot_string_error2 a few times under gdb with

set args --no-gui plot_string_error2.m
set detach-on-fork off
b octave_base_value::convert_to_str_internal
r

I include the backtrace when the hangs happen. The context before entering
Octave is opengl_renderer::draw => opengl_renderer::draw_axes =>
opengl_renderer::set_font

Regards 

This mean that rev 21803 helps but does probably not prevent all cases.

Regards

(file #37373)
