FreeBASIC Compiler

It gives a segfault if the default value is an empty string, and I try to
do anything with that string (Printing or assigning).

Try this code:

---- test.bas ----
Type TypeA
v As String
Declare Constructor(v As String = "")
End Type
Constructor TypeA(v As String)
'' Comment this out and no segfault occurs.
Print v
End Constructor

Print "Declare"
Redim Shared iplist() As TypeA
Print "Size"
Redim iplist(1 to 2) As TypeA
Print "End"
---- End File ----
