Thanks.

Now, executable scripts need "-f" to be run directly ( ./script.apl ).

   #!/usr/bin/env -S apl -s -f

Otherwise, apl waits for stdin input (the script is not executed),
and apl cannot be terminated by killall apl — only by ")off" or kill <PNUM>.

It happened always, for ⍵>35 around. But the errors were different
for every argument value. See attachment.

Thank you for the explanation. It was useful.
After some testing, my conclusions are:


1) The errors seem be caused by parallel processing. I was using

   ./configure DEVELOP_WANTED=yes CORE_COUNT_WANTED=2

   (Now I run ./configure without options.)


2) With  make develop / make apl.lines / ./apl, the program worked fine
   inside src/ directory.


3) I got the same bugs after "sudo make install", running /usr/local/bin/apl.


4) No problems if "sudo make uninstall" before reconfiguring and recompiling.
   That suggests me that some residues of previous versions were remaining.


5) README-2-configure suggests running

   autoreconf --force --install
   ./configure
   make

   but I need also calling autoupdate:

   autoupdate
   autoreconf --force --install
   ./configure
   make


Best regards,
Hudson
