We encountered a stack overflow in our application that uses Firebird
Embedded. The overflow occured during restoring a database (100%
reproducable).

The stack reserve size of our process was 1 MB. Increasing it to 2 MB
fixed the problem. The Firebird Server process seems to use a stack
reserve size of 2 MB, so this is probably the recommended value.

My questions:

1. Is there official advice on setting the stack size when using
Firebird Embedded (i.e. is the requirement of "/STACK:2097152"
documented)?

2. Is 2 MB enough in all cases, or can we encounter a backup file which
causes a stack overflow during restoring even with the 2 MB setting?

Best regards,
Antti Nivala
