However, if I declare an allocatable array as a type component as follows: program test_gdb implicit none type :: a real :: b = 1.0 real, dimension( : ), allocatable :: c end type a type( a ) :: d allocate( d%c( 3 ) ) d%c = 1.0 print *, d%c end program test_gdb gdb issues the following error message when trying to print d%c: (gdb) p d%c Cannot access memory at address 0x3f800004 Interestingly, if I remove the first type component (real :: b = 1.0) gdb works correctly. Btw, when can we expect the Fortran enhancements to be included in main-line gdb?
