Major bug on G2
When making some test to optimize some code I got a very nasty bug

Program leads to "reboot screen"
"Your HP Prime had a
problem and will
will reboot in 3 seconds" ...

got the trouble even after CFO,reset finally the problem disappear ... then reappears

AFTER CFO-ON, format C:, reset
mem INFO gives Memory 246.86MB, Storage 461.68MB
next one, reset
mem INFO gives Memory 246.93MB, Storage 461.59MB
next one with format C:, reset
mem INFO gives Memory 246.88MB, Storage 461.68MB

So it seems that I definitely lost 256MB of ram Sad
--EDIT--
Or I was misreading the info at first, I think that I saw Memory about 400MB but
as it seems that the G2 only got a 256MB ram chip so I was certainly misreading ...
So ram seems ok
--EDIT--

All tests seems ok

First run after CFO format reset was ok, then the pb re-appear (running prog with calc connected on USB)

Nexts runs leads to reboot too even with calc disconnected from USB

Program follows as source (sorry for the size)

Binary at bug at end of page, test42-bug.zip, reboot picture there too

On a windows 10 Virtual Prime Build 2.1.14181, no problem at all

Re-flashing the firmware does not change anything.

RE: Major bug on G2
It looks like the BREAK; command in a program, is the cause of this issue.
Go to HELP, and search for BREAK.
The example gives you a program Demo_BREAK.
When running this program, the Prime reboots.

I have had to patch several programs, not to use BREAK; and instead of that,
construct some other condition to leave a loop.

Is there a chance to get that fixed in the next firmware release?

Thanks in advance.

I tried this (Demo_BREAK) again with a clean (Format C) Prime G2.
=> Same behavior => Calculator resets.

Can anybody confirm this issue, or does my Prime G2 hava a hardware issue?

Thanks in advance

RE: Major bug on G2
Confirmed!
Paperclip reset was not necessary.
Reboots after some time.

My G2 does the same thing. It takes a while but it resets itself with no paperclip needed.
