Btw, we do not die during inlining, but during optimization which is confronted
with one gigantic basic block, as all BBs after inlining are merged by fixupcfg
;)
Oh, and we die during RTL optimizations... but I wonder why we are not able to
free up some memory before (lower gc params help for this, and we enter greg
with 250MB used and it still wants
cc1: out of memory allocating 1134939624 bytes after a total of 43487232 bytes
So, more something for Matz/Vladimir.
