Plus42 Equations, Preview Release

[JohanNeven]

While testing a Plus42 (Linux version) program, I encountered a fatal program shutdown issue.

Following program cutout gives the necessary and sufficient elements to cause this problem.

Code:

00 { 56-Byte Prgm }
01▸LBL "TEST"
02 LSTO "AA"
03▸LBL 01
04 CLMENU
05 "L0"
06 KEY 1 GTO 81
07 MENU
08 STOP
09 EXITALL
10 GTO 01
11▸LBL 81
12 "L1"
13 LSTO "TYP"
14 LASTO "UN"
15 CLMENU
16 KEY 1 GTO 21
17 MENU
18 STOP
19 EXITALL
20 GTO 01
21 .END.

It uses a two-level menu in combination with LSTO and LASTO. In the second level, pressing RCL or STO causes the application to stop suddenly. I suspect this happens when showing the possible variables for STO or RCL. Removing 1 line of lines 02, 13 or 14 makes the problem go away.

I tested the same program also in the Android version. There it gives no problem.
