Right now, i have come across an issue concerning GDB. This issue makes it impossible for me to use GDB within Eclipse for the moment. So I tried to see if I can reproduce this issue. I am running Eclipse on a 32 bit Windows Vista Computer as well as on 64bit Windows 8 Machine. I am using GFortran and GDB with the latest MinGW installation. Both computers show the same issues. So here is what happens. Step 1: I have code that contains a Derived Type for a linked list: 1 : PROGRAM GDB_Fail 2 : 3 : IMPLICIT NONE 4 : 5 : TYPE :: Test_Node 6 : TYPE(Test_Node), POINTER :: next => null() 7 : INTEGER data 8 : END TYPE 9 : 10: TYPE(Test_Node) :: node_test 11: 12: node_test%data = 4 13: 14: END PROGRAM GDB_Fail Step 2: Setting a breakpoint at line 12 (gdb) br 12 Step 3: Run the program Step 4: Inspect the node on its next item (gdb) print node_test%next PTR TO -> ( Type test_node PTR TO -> ( Type test_node PTR TO -> ( Type test_node PTR TO -> ( Type test_node PTR TO -> ( Type test_node PTR TO -> ( Type test_node PTR TO -> ( Type test_node PTR TO -> ( Type test_node PTR TO -> ( Type test_node PTR TO -> ( Type test_node PTR TO -> ( Type test_node PTR TO -> ( Type test_node PTR TO -> ( Type test_node This is the point where it fails and GDB apparently tries to evaluate the next pointer of the next pointer of the next pointer. The only way to stop is Ctrl-C. The output is exactly what I get from within Eclipse as well. The same program written in C can be debugged without any trouble. For me it looks like there is an issue with GDB inspecting recursive Derived Types.
