[fpc-devel] about #0035991, fpc 3.2.1 still crash lazarus 2.0.10, 2.0.11

[Ondrej Pokorny]

Hello Bald,

it is not possible to support the latest FPC trunk in already released 
Lazarus versions (2.0.10).

If you want some bug fixes to be merged into the stable branch 
(currently 2.0.11), you can list the revisions here:
https://wiki.freepascal.org/Lazarus_2.0_fixes_branch

I did it for you now for the two revisions of issue 35991.
