[Bug tree-optimization/42139] Compiling firefox trunk with 4.5 fails with 'out of memory allocating 4072 bytes after a total of xxx bytes'

[jason at gcc dot gnu dot org]

------- Comment #3 from jason at gcc dot gnu dot org  2009-12-16 13:52 -------
But the actual OOM comes while optimizing xml_setchildren, from an obstack
allocation in bitmap_element_allocate during compute_may_aliases after running
the alias pass.  dump_memory_report says 1452M allocated from GC,
obstack_memory_used says 949512960 bytes allocated for the bit_obstack, and ps
says 3062624k virtual memory size.

I'm done looking at this now.
