[Lazarus] spilling related accesviolation when rebuilding lazarus (extgraphics) with 3.3.1

[Marco van de Voort]

For a while now I have had problems building custom lazarus.

The error is always something spilling related, and this case in 
extgraphics, code that uses an open array of tpoint.

I tried to copy and paste the relevant code in a separate unit and 
compile with the arguments that lazarus lists of "build ide", but no 
success.

Anybody also has this? I have seen this since december occasionally, but 
recently it got really more frequent.
