>Description:
The debug symbol information is incorrect for unaligned 64-bit fields in a struct.
>How-To-Repeat:
Compile with "gcc -o t64 -gdwarf-2 t64.cpp", run gdb on this program and notice that the difference between the address of Global_struct.bbb and Global_struct.aa is 8 when it should be 4. Displaying Global_struct or Local_struct at the end of this program will result in the incorrect value for field bbb being displayed.
