           Summary: explosion in time and stack usage when using -ggdb
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: matt@use.net


When compiling the attached preprocessed source with -O1 -ggdb, an explosion in
memory usage occurs. If I remove the -ggdb, the problem doesn't happen. This
seems to affect 32-bit targets more deeply:
g++ -march=pentium4 -ggdb -O1 -c bts.i

Oddly, the problem doesn't happen when running under valgrind. The problem does
happen under gdb, though, so that's something.
