            Bug ID: 58315
           Summary: [4.8/4.9 Regression] Excessive memory use with -g
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Keywords: memory-hog
          Severity: normal
          Priority: P3
         Component: debug
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rguenth at gcc dot gnu.org

Compiling the PPL testsuite, specifically MIP_Problem/mipproblem1.cc, with
-O2 -g makes GCC use nearly 6GB of memory (followed by GAS needing 6.5GB
of memory to assemble the result).

Dropping -g results in instant gratification.
