15.0.47 Access violation during options>string conversion

[FredS 138]

This version has so far worked well on Win7, but when altering options there is (repeatable) this:

Access violation at address 500C4163 in module 'rtl280.bpl'. Read of address 17775000.

[500C4163]{rtl280.bpl  } System.TypInfo.GetEnumName (Line 1630, "System.TypInfo.pas" + 20) + $4
[5005FAC2]{rtl280.bpl  } System.UTF8IdentStringCompare (Line 17746, "System.pas" + 3) + $4
[50CED2C2]{vcl280.bpl  } Vcl.StdCtrls.TCustomCombo.GetItemIndex (Line 4276, "Vcl.StdCtrls.pas" + 4) + $11
[500C40FF]{rtl280.bpl  } System.TypInfo.GetEnumName (Line 1616, "System.TypInfo.pas" + 6) + $C
[170EDFBD]{mmx_bds22.dll} PropInfo.TObjectAccess.GetValues (Line 507, "PropInfo.pas" + 7) + $29
[170ED74C]{mmx_bds22.dll} PropInfo.CopyProperties (Line 198, "PropInfo.pas" + 12) + $9
[1735F78F]{mmx_bds22.dll} PascalOptionsFrm.TMMXPascalOptionsForm.ApplySettings (Line 104, "PascalOptionsFrm.pas" + 1) + $14
[17248612]{mmx_bds22.dll} MMX.Options.Form.TOptionsPage.ApplySettings (Line 720, "MMX.Options.Form.pas" + 2) + $6
[17247CA1]{mmx_bds22.dll} MMX.Options.Form.TOptionsShellForm.ApplySettings (Line 435, "MMX.Options.Form.pas" + 3) + $F
[17247BC1]{mmx_bds22.dll} MMX.Options.Form.TOptionsShellForm.ApplyBtnClick (Line 389, "MMX.Options.Form.pas" + 2) + $2
[50CC8223]{vcl280.bpl  } Vcl.Controls.TControl.Click (Line 7660, "Vcl.Controls.pas" + 9) + $8
[50CF03F6]{vcl280.bpl  } Vcl.StdCtrls.TCustomButton.Click (Line 5875, "Vcl.StdCtrls.pas" + 3) + $2
[50CF1580]{vcl280.bpl  } Vcl.StdCtrls.TCustomButton.CNCommand (Line 6510, "Vcl.StdCtrls.pas" + 1) + $B

Similar may have happened while altering 'Metrics' but this one is repeatable when changing the 'String Identifier Prefix' and either clicking 'Apply' or 'OK'.

 

It won't save the changes, after a restart if I go in and ONLY change this single option it works. Changing 3 or 4 using 'Apply' a couple of times and coming back to this ends the same way..

I'm afraid that may be out of my scope here. Delphi 11 states it requires Win10+ and the error occurs with Win7 inside System.TypInfo.GetEnumName, but it does not happen here in Windows 10.

 

If you can reproduce with Win10 I will try my best to reproduce it on my side. Sorry, but I'm not going to install Delphi 11 on Win7 here to trace a bug in an unsupported environment.

Thanks, but D11 isn't ready to leave the 'Sandbox' yet but maybe eventually..

Unfortunately a similar Error now happens in Berlin on Win7:

Fine (well, somehow). 

Does it happen only on Win7 or can you see that on Win10, too?

Still using MMX 14.05 on Win10 🙂

 

Which makes it easier to ignore all those parsing errors!
That new RED icon makes you look at all those directives which are ignored..

 

I may just revert to 14.05 on Win7 and leave that alone, if no other users are reporting these issues and you can't reproduce then we may just leave it at that.

 

I am noticing some slow down since installing 15.0.47 in D11.. and LSP issues.
Could be those exceptions and a reboot is needed..
