Hi all. I have a strange issue that I am not sure what is going on. I use FPC / Lazarus mainly on Raspberry Pi ARM Linux. I got a new 8GB pi and installed Trunk FPC and Trunk Lazarus. I then installed the BGRA Controls and found that the controls did not behave correctly. I logged an issue with the developer and after a lot of testing he said it seems to be a FPC issue on ARM Linux. Here is the link to the issue. https://github.com/bgrabitmap/bgracontrols/issues/113 I wrote some test code and found that the values being sent from the calling procedure does not end up correctly on the called procedure side if you use a calculation inside the procedure call. If I create new variables and do the calculation first and then use the variables inside the procedure call then all works fine. I found the same issue now with different version of FPC also not only the 3.3.1 version. 3.2.2, 3.2.0 also does this. Here is a sort code extract from the control code. I print the values before the call ``` writeln('Width : ' + floattostr(Width)); writeln('Height : ' + floattostr(Height)); writeln('Half Width : ' + floattostr(Width / 2)); writeln('Half Height : ' + floattostr(Height / 2)); FBitmap.Canvas2D.arc(Width / 2, Height / 2, Height / 2.5, 0, pi * 2, False); ``` As you can see there are calculations inside the call like Height / 2 Then on the receiving procedure side I print what is the values of X and Y as passed in. ``` procedure TBGRACanvas2D.arc(x, y, radius, startAngleRadCW, endAngleRadCW: single; anticlockwise: boolean); var pts: array of TPointF; temp: single; pt: TPointF; rx,ry: single; len1,len2: single; unitAffine: TAffineMatrix; v1orig,v2orig,v1ortho,v2ortho: TPointF; startRadCCW,endRadCCW: single; begin writeln('X in arc : ' + floattostr(x)); writeln('Y in arc : ' + floattostr(y)); v1orig := PointF(currentState.matrix[1,1],currentState.matrix[2,1]); v2orig := PointF(currentState.matrix[1,2],currentState.matrix[2,2]); ``` And here is the output. Y should be 100, yet it is 3.390625 ``` Width : 200 Height : 200 Half Width : 100 Half Height : 100 X in arc : 100 Y in arc : 3.390625 ``` is there some setting or switch that should be set so that this does not happen on FPC?
