it should be noted that a database corrupted for this reason has yet
to be seen. The Firebird engine tends to detect problems in the memory
structures and shut down without writing the problematic structures to
disk.

Also, the very same potential problems apply when you use UDFs, yet I
don't see people discouraging the use of UDFs as frequently as they do
with fbembed.
