It gets into an infinite memory eating loop for me with 2.95.3 20010315 (SuSE).
However, here's some more fodder for bug fixers: with 3.4, the loop is
these functions, apparently calling each other in infinite ways (I just
killed cc1plus at an arbitrary point, so your stack trace will look
differently; at this time, gdb showed me the first ~9000 stack frames,
before I had to kill it...)
