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.
