A simple example shows the problem: program test implicit none integer i character(16) abc abc = "abc" i = 7 end program
Compile with: gfortran -g -O0 test.f90 Run with gdb and "whatis abc" produces: type = character(kind=1) (16) That is, gdb thinks that the variable abc is an array of length 16 with each component in the array being a singe character. I verified with the totalview debugger that the problem was with the compiler and not gdb. Interestingly enough, version 4.1.1 does *not* have this problem. This bug definitely makes debugging a program more painful. -- Summary: Bad Dwarf debug information from gfortran for a character string.
