what release of gcc is used for bootstrap?
what are hard and soft limits, includig limits set in /etc/security?

Regarding /etc/security, I would have to ask.

Do you have the environment variable PSALLOC set on in the process building GCC?

I build on AIX systems with data, stack, and memory size unlimited, 2GB memory,
PSALLOC unset.

If running stage1 genattrtab compiled without optimization requires more memory,
then it requires more memory.  The value reported seems quite large, but the
scheduling change would not cause a huge increase.

IA-64 builds have failed for me due to memory building its automata.  Building
GCC requires a lot of memory for some steps.  Some targets require a lot of
system resources for a complete bootstrap.

This PR appears to be a process resources issue, not a bug in mainline GCC.  GCC
3.3 and 3.4 could be doing something strange with memory usage or the build
could be interacting with AIX 4.3.3 malloc in a strange way.

I do not understand what type of solution you are expecting.

out of memory allocating 222496 bytes after a total of 4161584284 bytes
make[2]: *** [s-attrtab] Error 1

If the value reported is correct, then there is clearly a problem as
we are reaching the limit of addressibility.  I'll explore further but
it won't be until after Christmas.  At this point, I don't know the
cause.  However, reverting the scheduling change allows genattrtab to
complete successfully.

PSALLOC isn't set.

genattrtab runs successfully with the following limits:

ginyu% ulimit -a
cpu time (seconds)         unlimited
file size (blocks)         unlimited
data seg size (kbytes)     unlimited
stack size (kbytes)        131072
core file size (blocks)    unlimited
resident set size (kbytes) unlimited
virtual memory size (kb)   unlimited
file descriptors           2000

Thanks,
Dave
