This specific case is mentioned in the "Host/Target specific installation notes for GCC" section on AIX: out of memory bootstrap failures may indicate a problem with process resource limits (ulimit). Hard limits are configured in the /etc/security/limits system configuration file. On AIX, root has resource limits like every other user. Make sure that you are viewing the hard limits, not the soft limits. I suspect that the hard limits are capped. Stack, data, and memory need to have large limits to bootstrap GCC. Also, building as root probably is not a good idea. By the way, the 4161652492 does not represent the total amount of memory currently allocated, some of the memory has been returned during the process execution. I also would recommend not changing the Make options. David
