Argument error on "read"

[rletocart]

Hi guys,

I built successfully xHarbour under debian 9,10,11,12 and alpinelinux, both for aarch64 and x86_64, via docker for better automatization.
My apps run smoothly under this archs using GT_CRS, GT_TRM and/or GT_CGI.

I lastly got an annoying problem with random errors like "argument error: <>" on a simple read of a string variable... Only some variables, always at same place under any arch.

static datvisu:=""
...

proc majart
...
        if empty(datvisu)
            datvisu := m->dateoftheday-(m->avgsales*30)
            datvisu := beginofthemonth(datvisu)
          endif
          @ row(),col() get datvisu
          read
...          

line read cause argument error: <>

when compiling with xharbour version older than 2023 (I don't have exact date), this is OK... Any idea would help.
Thank you guys for this hard work, I'm using xHarbour project since 2000s ;) (Who could at this time say that 20 years later, we can always run our apps, on rpi5 aarch64 inside a docker which did not exist then :))

works even for macosX (darwin), IDXLNET is inside job, can ben ignored
