<<And a couple of final questions, what optimisation level are you using during the build?
32bit or 64bit Firebird?
64-bit. I have not changed any optimisation flags so it looks like it's being compiled with -O1 (from builds/posix/prefix.darwin_x86_64)>>

2.5.8 64bit Firebird now compiles with -O0 because of a problem with optimisation in fbintl that caused
Firebird to crash...

I have not seen any crashes with Firebird, but I will compile up 2.5.8 and see if it helps.

Thanks,
