Details:

Hi!

Flatpak 6.3.0 on linux mint.

I made this ... ridiculous thing fuh yoo:

debug_on_error(1)
debug_on_warning(1)

NOVER = NLIM = 10000;
nsucc = -666;  nchg=0;
j = 0;  trip = 0;
while((j < 100) & nsucc);
  j++;

  if(nchg < nsucc) disp("Huh 01X???")  endif

  nsucc = 0;
  k = 0;
  while((k < NOVER) & (nsucc < NLIM));
    k = k + 1;

    if(nchg < nsucc) disp("Huh 1???")  endif
    if(rand < .001) nsucc++;  nchg++;  endif
    if(nchg < nsucc) disp("Huh 5??")  endif
    endwhile

  if(nchg < nsucc) disp("Huh X1???")  endif
  endwhile

[j k nsucc nchg]

Running it will (eventually) trigger a 
  "Matlab-style short-circuit operation performed for operator &" 
warning, but pointing to line 19, instead of either of the while(s)

Enjoy!
Doug
