Can preview PELA-technic-block when h greater than 1

[Aeronaut]

Describe the bug

• Loading file "PELA-technic-block.scad"
• In Customizer Set: Technic Block -> h to everything greater 1

No block previewed, OpenSCAD Application freezes completely.

When [Edit] -> Preferences -> Advanced -> Settings -> OpenSCAD Language Features -> [v] Stop on the first waring
I see this WARNING with TRACE:

Thanks, I'll take a look at duplicating with a new version of OpenSCAD
