A.6 AIX-Specific Considerations

On AIX, the resolver library initializes some internal structure on the first call to get*by* functions, which are used to implement GNAT.Sockets.Get_Host_By_Name and GNAT.Sockets.Get_Host_By_Addrss. If such initialization occurs within an Ada task, and the stack size for the task is the default size, a stack overflow may occur.

To avoid this overflow, the user should either ensure that the first call to GNAT.Sockets.Get_Host_By_Name or GNAT.Sockets.Get_Host_By_Addrss occurs in the environment task, or use pragma Storage_Size to specify a sufficiently large size for the stack of the task that contains this call.
