Hi,
I am working on a project that is the property of a fellow Rb user
that I am assisting. It has been written in Rb 5.5.5 and compiles and
operates fine in that version.
When I attempted to run it in Rb 2007r1, it would not compile in the
IDE and produced one error. This error concerned a very long method
(2069 lines that uses a TextOutputStream, about 206 If...Then
conditionals, and a fair amount of string concatenation in each of
the WriteLine statements. Nothing really seems out of order in the
coding other than the fact that it definitely could use a lot of
refactoring, which I was intending to do.
The error reported was:
Location: Window1.WriteData, line 2069
Error: This method uses 44k of stack space, but the limit is 32k.
End Sub
Line 2069 is off the scope of the 2007r1 code editor and is actually
the hidden End Sub line. Line 2068 is the last visible line in the
method.
In an attempt to discover where the problem might be I tried it in
earlier versions of Rb. In both Rb 2005r4 and Rb 2006r1, the project
compiled and operated correctly. In Rb 2006r2, it failed to compile
but said that the method used 39k of stack space. In Rb 2006r3,
2006r4 and 2007r1, the stack space used was 44k.
After removing about 50% of the If..Then conditionals, it would then
compile in 2007r1. ( I probably could have removed less code)
I understand that the later versions of Rb do a better job of error
checking than 5.5.5, but why the discrepancy between Rb 2006r2 and
2006r4 when running the same method.
I tried saving the project in 2005r4 and 2007r1 but the same thing
happens.
The actual 5.5.5 project, opened in 2005r4 and 2006r1, operates fine
and shows no stack errors.
I will submit a bug report with the project as a private example if
the owner permits.
In the meantime, does anyone have any similar experience or knowledge
that they could pass on as this is a first for me.
