[Bug debug/40012] New: Bad debug info for local variables

["gcc at magfr dot user dot lysator dot liu dot se" <gcc-bugzilla at gcc dot gnu dot org>]

Given the attached program compiled with

gcc -ggdb3 -o dlmod dlmod.i

the DW_AT_location for the variable 'problem' seems to be off by 16 bytes, so
when I try to examine the variable from the debugger that returns the wrong
value.

Below is some information about my compiler:

svnversion reports that I am using revision 147075.
