The next release will be out during one of the coming weeks, and is  
currently at RC1 status. This means that only regressions are still  
possible candidates for inclusion in the final release. Since your bug  
occurs with FPC 2.2.4, that is not the case... On the other hand, have  
you tried compiling it with FPC 2.4.0rc1? Maybe the bug is already  
fixed.

If it doesn't have any external dependencies and preferably is cross  
platform (endian safe, no reliance on 80 bit floating point precision  
nor on intermediate calculations being performed using 80 bit  
precision), I think that could indeed be a good addition.
