I tested in Uspace, Preempt RT and it loaded without an error, so that looks good so far. I wonder why it worked in RTAI?

I just tested and lcd does load without any error, so I went on and configured my fmt_strings and I found another serious bug
My fmt_strings has actually 4 pages, and I can call them with
setp lcd.00.page_num 0
setp lcd.00.page_num 1
setp lcd.00.page_num 2
setp lcd.00.page_num 3
But if you call setp lcd.00.page_num 4
you get
So all crashed, no more reaction etc.
Do you want me to open a issue in github?

I would open an issue on github for sure. I probably have the hardware to test this (I should as a Mesa Dealer)

I think lines 266 and 267 need to swap places:
github.com/LinuxCNC/linuxcnc/blob/master...omponents/lcd.c#L265
Or. possibly, an explicit range test on page_num before doing anything at all.
It notices the problem the first time through but then carries on regardless next thread cycle.
