Bug in StrReplace()

[Carlo Hogeveen]

Just like any other string command, if StrReplace() creates a string longer than the maximum string length, then it should just cut
the excess off, and not abort the editor with "I'm sorry, Dave. I'm afraid I can't do that.".

proc Main()
integer i = 0
string r [MAXSTRINGLEN] = ''
string s [MAXSTRINGLEN] = ''
for i = 1 to MAXSTRINGLEN
s = Format('':i:'x')
Message('i=', i; 's=', s)
KeyPressed()
Delay(1)
r = StrReplace('x', s, 'yy')
r = r // Pacify compiler.
endfor
PurgeMacro(CurrMacroFilename())
end Main

Hi Carlo,

I tried the macro below on my Linux TSE 4.50 and it counted up to 255
and stopped without aborting. Is that what you would expect?

Trump has proved he can fool enough of the people (aided by circumstances)
to get elected US president. But what happens when his plans and boasts
go awry. For example, mass deportations and huge tariffs will do a number
on the economy.

Hi Fred,

Fair point.
My tests say:
In the Windows GUI and Console versions of TSE the example macro aborts at "i=131" while apologizing to Dave.
In WSL's Debian with the Linux version of TSE the macro aborts on a "Segmentation fault" at "i=131".
In a Debian desktop and in a Ubuntu desktop with the Linux version of TSE the macro does not abort.

The StrReplace() demo macro not aborting in Linux desktops turns out to be a red herring.
I had an "old" Linux TSE installation in my Linux desktops.
I suspect Fred does too.

Further tests say that from TSE v4.50.1 (12 Dec 2024) onwards the demo macro starts aborting in all environments.

TSE's read.me file states that in v4.50.1 bugs in StrFind() were fixed.
I suspect the new StrReplace() bug is a side-effect of that.
