[Bug rtl-optimization/43058] [4.5 Regression] var-tracking uses up all virtual memory

[wilson at gcc dot gnu dot org]

------- Comment #16 from wilson at gcc dot gnu dot org  2010-03-23 00:58 -------
The testcase checked into mainline is causing kernel panics on my debian
testing ia64-linux machine when I run the gcc testsuite.  The kernel panic is
coming from the out-of-memory killer, when it runs out of processes to kill.  I
have 2GB main memory and 2GB swap.  I tried a x86-linux hosted cross compiler
to ia64-linux, and I see the cc1 process uses 3GB before the kernel kills it. 
I suspect a 32-bit x86-linux process can't use more than 3GB.  I don't know how
much memory is needed for this testcase, but it is clearly too much.

ia64-linux isn't a primary target, so this is maybe not P1 if only ia64-linux
is still broken.
