If a variable is passed to function in FORTRAN as an argument the variable is treated as an array with rank zero. GDB currently does not support the case for assumed rank 0. This patch provides support for assumed rank 0 and updates the testcase as well. Without patch: Breakpoint 1, arank::sub1 (a=<error reading variable: failed to resolve dynamic array rank>) at assumedrank.f90:11 11 PRINT *, RANK(a) (gdb) p a failed to resolve dynamic array rank (gdb) p rank(a) failed to resolve dynamic array rank With patch: Breakpoint 1, arank::sub1 (a=0) at assumedrank.f90:11 11 PRINT *, RANK(a) (gdb) p a $1 = 0 (gdb) p rank(a) $2 = 0
