Title: Crash with STR
Post by: Brian Alvarez on November 15, 2018, 06:30:53 AM

This code is crashing when i add a second parameter. I suspect is is because of recursion, how can i fix this? how can i make sure it calls system str instead of calling the function itself?

Code: [Select]

' Enter the stock code and functions here.
FUNCTION STR(double v, sys d) as string
    if v < 0 then
        return str(v, d) '<-- crash here, removing second parameter fixes it.
    else
        return " " & str(v)
    end if
END FUNCTION

Brian,

This is an interesting dilemma which has arisen a few times before. I will see if there is an easy solution. Otherwise, the original str will have to be recreated using another name, to avoid recursion.

I agree, the parameters could not make a difference.

For the moment, PluriBASIC is generating the name as STR_ this has solved the issue for now.
It is working fine.

 This is a new crash with str. It only happens with 64 bit compilations.

Code: [Select]

long var = 2
print string(var, "0")
using a sys variable works fine.

It works fine for me. The bug causing this problem may be elsewhere. var is an overridable keyword, used in the RTLs but I don't think that is the cause.

This is the whole code that is consistently crashing:

Code: [Select]

$ filename "str_example.exe"

uses rtl64

long v = 2
print string(v, "0")

Try this one with the RTLs and see if the crash still occurs. I have tested it with my key software, and Self-compiling of course.

 This one works fine for this, but i think something changed because now my other code crashes.

 I will make more tests, maybe this one does something correctly and my old workarounds are
being trapped.

 Charles, this update (121kb) is giving me trouble with macro members:

Code: [Select]

ERROR: Unable to find macro member
WORD: )
IN: pbmain
LINE: 125
FILE: "main source
 Rolling back to previous DLL (139kb) makes everything work again.
