[fpc-devel] Anyone an idea were/how to look for the missing merge in 3.0.2

[J. Gareth Moreton]

Ah curses.  I fear it was something I did.  I don't like the idea of 
stepping through each revision until we find one that works.

https://bugs.freepascal.org/view.php?id=38294
https://bugs.freepascal.org/view.php?id=38334
https://bugs.freepascal.org/view.php?id=38339
https://bugs.freepascal.org/view.php?id=38343

Those ones relate to buggy optimisations in some way, but they might be 
a bit too late on to affect 3.2.0.

There are quite a few others too - hmmm.
