[fpc-pascal] Is there a recent change to TProcess?

[James Richters via fpc-pascal]

I am using ProgProcess to execute a program with data passed as parameters.
I'm adding the parameters with this:
 
         ProgProcess := TProcess.Create(nil);
         ProgProcess.Executable := 'cmd.exe';
         ProgProcess.Parameters.Add('/c');
         ProgProcess.Parameters.Add('start');
         ProgProcess.Parameters.Add('/wait');
         ProgProcess.Parameters.Add('"Message"');
         ProgProcess.Parameters.Add('CMD_Message.exe');
         ProgProcess.Parameters.Add(MyAnsiString);      // This is the
string I am sending
         ProgProcess.Options := ProgProcess.Options + [poWaitOnExit];
         ProgProcess.Execute;
         ProgProcess.Free;
 
 
If I compile it with:
Free Pascal Compiler version 3.3.1-15425-gf77b9fa4ef-dirty [2024/03/18] for
i386
I get what I expected:
    Sent: #$EE#$59#$20#$4D#$69#$6E#$20
Received: #$EE#$59#$20#$4D#$69#$6E#$20
 
If I compile it with:
Free Pascal Compiler version 3.3.1-16969-g798f2ba632-dirty [2024/11/28] for
i386
I get almost what I expected, but my #$EE is now been changed to #$3F   (and
all similar codes in the range of #$D0 - #$EF have been changed to #$3F as
well)
    Sent: #$EE#$59#$20#$4D#$69#$6E#$20
Received: #$3F#$59#$20#$4D#$69#$6E#$20

Does anyone know why this is?  I have tried it several times, if I compile
it with the trunk from 2024/03/18 it's fine, if I use the current trunk my
other program is receiving the wrong data. noted that I never re-compiled
CMD_Message.exe so it must be that my TProcess is now sending modified
parameters to my program.   
 
Is there any way to get TProcess in the current trunk to work the way it
used to?
