Re: [Bug-apl] Problems with shared variables

[Juergen Sauermann]

Hi Kacper,

thanks for reporting this. I believe I have fixed this in SVN 149.

There is now a system limit of 65kByte for the size of shared
variables, caused by the UDP protocol used for the communication
between processors.

Hi again,

There are still (r148) some problems similar to previously reported.
When passing a big array as shared variable, instead of being
truncated, now its tail is corrupted:

      0⎕SVO'X'
1
      X←489⍴2
      ¯2↑X
2 ¯1254096894

This suggests some nasty out-of-bounds read.
And, if array is even bigger, it gives the following error (after
a few seconds):

      X←3000⍴4
TIMEOUT on signal ASSIGN_VALUE_c
VALUE ERROR
      X←3000⍴4
      ^
