Now the problem not seems to be in string representaion.
The example code is below.
Calling the function "Test_DLL" from fad.dll without using
"Ada.Directories" works perfectly.
However, uncommenting the line <Path: String :=
Ada.Directories.Current_Directory;> gives non working variant.
Try to call the same function from the DLL now finishes by the DLL
crash.
The line <Path: String := Ada.Directories.Current_Directory;> do
nothing usefull in the example, but it must not invite the DLL to
crash.
Can somebody explain, what is wrong?
May be some compiler, builder, linker switches can be a cause of such
behaviour?
I am using the GNAT compiler from GPS+GNAT(MinGW) complect under
Windows XP.
The DLL was tested using the NI LabVIEW and "ExecDLL (http://
www.codeproject.com/KB/DLL/Execute_DLL_Function.aspx)"
Thanks for everybody for advices.

pragma Export(C, Pwd, "pwd");
function Pwd return String renames
Ada.Directories.Current_Directory;
function Test_DLL(A, B: in Integer) return Integer;
pragma Export(C, Test_DLL, "Test_DLL");
end FAD;

package body FAD is
function Test_DLL(A, B: in Integer) return Integer is
-- ==> Path: String := Ada.Directories.Current_Directory;
begin
return A*B;
end Test_DLL;
end FAD;
