           Summary: [3.3.2 regression] Huge memory use while compiling a C
                    file
           Product: gcc
           Version: 3.3.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: casteyde dot christian at free dot fr
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-gnu-linux
  GCC host triplet: i686-pc-gnu-linux
GCC target triplet: i686-pc-gnu-linux

While compiling Cinelerra, the file "quicktime/cmodel_default.c" 
makes gcc eats nearly 512Mo RAM. This doesn't happen with gcc 3.3.1 
(but cinelerra builds finally, whereas it didn't build with gcc 3.3.1). 
 
This doesn't happen without optimization flags used by the build 
system either. Preprocessed source and faulty flags appended. 
 
To reproduice : compile with 
 
gcc -c `cat flags` az.c
