GCC compile problem on HPUX 11.00 system

[Jenny Tao]

Hi, I am compiling one large file on HPUX 11.00 64bit system with GCC
3.0.  The compilation failed with 'virtual memory exhausted' error when
optimization is used.

Checking the memory usage , I can see the 'SZ' column in 'top' output is
only about 40M, but 'RES' has hit 940M when the compilation failed.

Does anyone have any idea why the resident size consumed is so much
higher than the 'SZ'? Any way to solve this problem?

Thanks

Jenny
