Crash occurs generally at the second `call add_point(drawing)`, sometimes at the first one. If we write: ```fortran do call pending_events() if (run_status == FALSE) exit call g_usleep(100000_c_long) ! So we...

x17f.f90, copied from /usr/share/plplot5.15.0/examples/fortran , is successfully running on the same (virtual) machine: `$ gfortran x17f.f90 $(pkg-config --cflags --libs plplot-fortran)` with the following graphical drivers: ```bash < 1> xwin X-Window...

hl_plplot17e_gto.f90 crashes also when the line `call gtk_widget_queue_draw(area)` in the function `add_point()` is commented.

More information with GFortran 12.0.1 in latest Fedora Rawhide, here for `hl_plplot17e.f90`: ```gdb ... #11 plP_drawor (x=, y=) at /usr/src/debug/plplot-5.15.0-37.fc36.x86_64/src/plline.c:515 xt = 0.20000000000000001 yt = 0.034899496702500969 #12 0x00007fa50292173d in c_plstripa...
