Why does MATLAB crash when I try to export a figure with a y-axis label on a RedHat 8 machine?

Why does MATLAB crash when I try to export a figure with a y-axis label on a RedHat 8 machine?

I have plotted some data and added a label to the y-axis using the YLABEL function.When I try to export the figure to a file, MATLAB crashes.To observe this behavior, execute the following code on a RedHat 8 machine:

figure(1);

ylabel('Y');

print -dpng test.png

This produces a crash that begins with the following lines:

This has been verified as a a bug in MATLAB 6.5 (R13) and later versions in the way figures with y-axis labels are exported on RedHat 8 machines.

Currently, to work around this issue, try the following:

1) Export to another format. In particular, exporting to one of the PostScript formats should work.

2) Change the "Rotation" property of the y-axis label text object. The problem appears to be related to text objects with their "Rotation" property set to 90. Try setting the rotation to a slightly different value, like 89 or 91. This is accomplished by the following commands:

figure(1);

ylabel('Y', 'Rotation', 91);
