As a side note:
For x86_64,both FPC 3.2.0 and FPC 3.2.2 have a bug in the optimizer.
From current observation this issue is extremely rarely triggered. However, if the IDE for x86_64 is compiled with O2 or higher, then at least FpDebug will be broken (The affected code is a generic in LazUtils: TLazThreadedQueue or TLazFifoQueue).
Other parts of the IDE have not yet been observed, however even if the bug is in effect, the broken code needs to be executed with very specific arguments. Therefore, actual faulty behaviour could occur rather seldom. Yet, as any bug, it can strike at any time.
Compiling with -O1 is save
Compiling with -O2 -OoNoPeepHole should also be save..
It is recommended for x86_64 users, to build your IDE with -O1 only.
This issue also affects 2.0.x (or potentially other code) if build with 3.2.0 or 3.2.2.
Since the triggers for this issue (complier going wrong, and resulting broken code actually failing) are extremely complex, not every IDE build (with 3.2.0/2 and -O2 up) will immediately show symptoms. It is possible that an affected build runs without issues, or fails once every few month only.
As for your own projects, you need to come to your own decision. I have not seen any reports of this issue (other for the IDE), and 3.2.0 has been out for a good time.
Yet, no guarantees.
The issue is fixed in 3.2.3, so with the upcoming 3.2.4 this problem will be gone.

32 bit users should not be affected by this.
Non intel platforms should also not be affected.
