1. Phix simple_paint demo crash

The following is wrt Phix 0.7.9 (32 bit Windows) and simple_paint.exw.

When started, the program window appears Ok but any attempt to draw in the image results in a Windows failure notification. ie "p.exe has stopped working" (with a kind offer to search online for a solution [declined ]).

I wonder if this is reproducible elsewhere or local to my machine. If it's a reproducible problem I could have a poke about and see if I can narrow it down a bit.

I have the original 'TecGraf' C version of the program and it compiles and runs Ok.

When I run simple_paint.exw from pdemo, I get this output:

C:\Phix\demo\pGUI\pGUI.e:3284 in function IupConfigLoad() 
  (warning: lineno of -1 for era of #62895BA3) 
fatal exception [MEMORY VIOLATION] at #62895BA3 
    config = 15699968 
    errcode = <novalue> 
... called from C:\Phix\demo\pGUI\simple_paint.exw:2161 
 
Global & Local Variables 
 
--> see C:\Phix\demo\pGUI\ex.err 
Press Enter... 

ADDED: The 2048 demo works fine for me.

Ah, there was something introduced in IUP 3.24, try this:

procedure ensure_config_file_exists() 
    -- Bugfix for 3.24 (reported) [remove when >3.24 is released] 
    string f = join_path({getenv("HOMEDRIVE"),getenv("HOMEPATH"),"simple_paint.cfg"}) 
    if not file_exists(f) then 
        integer fn = open(f,"wb") 
        close(fn) 
    end if 
end procedure 
 
    config = IupConfig() 
    IupSetStrAttribute(config, "APP_NAME", "simple_paint") 
 
    ensure_config_file_exists() 
 
    {} = IupConfigLoad(config) 

Technically 3.25 has just been released, this week, but I have not downloaded it or anything yet.

Regards,
Pete

PS: I wouldn't get that problem here, because I've already got a simple_paint.cfg file
