I'm facing a strange issue, I don't know if it's StreamIO or
TMemoryStream. The following program, compiled with fpc
Free Pascal Compiler version 3.2.0-beta [2019/04/26] for i386
(I checked trunk and I don't see changes in streams or streamio)
I tested your program with trunk, and it works OK.
Thank you for testing, maybe it's time to upgrade the compiler.
Per chance, do you know what could possibly have changed to fix the
issue?
I'm using svn revision 41937 and I had a quick look at the changes in
the repo, the only thing that caught my eyes is the ";overload;" added
to the Read/Write methods of
THandleStream/TCustomMemoryString/TMemoryString
Well, lots of things changed in trunk regarding stream handling (Delphi
comapatibility) but these things were not merged to 3.2, since they require
compiler changes, and these changes were also not merged to 3.2, since
they're quite invasive.
The 'overload' just means that the compiler will not stop searching in the
current class but will consider parent classes as well. This should not
change the behaviour in case the stream variable is declared as TSTream.
(as should be the case inside assignstream)
My bad, I'm not on trunk, I'm on the fixes_3_2 branch :-(
Sorry for the confusion.
I checked out the latest version of that branch (I'm not confident
enough to use trunk in production) but it has the same problem.
Oh, well, I can use shortstrings in this application, though it really
puzzles me (setting position:=0 doesn't change anything yet it causes
this problem).
Bye
