             Bug #: 55808

           Summary: excessive memory usage from gcc 4.7.2 when compiling

                    mame source code

    Classification: Unclassified

           Product: gcc

           Version: 4.7.2

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: c

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: mister.free...@laposte.net





I notice that gcc 4.7.2 uses very excessive amount of memory when I compile the

mame source code ( an arcade emulator ) :



http://mamedev.org/release.html



I have archlinux 32 bits on a virtualbox ( 4.2.6 version ) virtual machine (

CPU dual core 3.3 Ghz, 1 Gb ram and 512 Mb swap partition ),



with PC configuration who have little memory ( 1 Gb for example ) and little

swap partition ( 512 Mb ) it is impossible to compile mame, because the memory

usage is excessive, I monitored the usage of the memory and gcc often takes

almost 2 Gb of ram,



if the system memory is too low ( 1 Gb physical ram and 512 Mb swap partition )

it will cause a fail with this error message :

Aborting... 





if I use an older version of GCC ( for example : gcc 4.4.5 ) I can compile mame

without problems on systems who have low memory ( 1 Gb and 512 Mb swap

partition ), so it's clearly a regression bug in gcc 4.7.2,



and check the first comment here ( padremayi ), same error with gcc 4.7.2 :

we need to improve the memory consumption of gcc
