Subject: Memory leak in 1.8.6-p287

We've noticed a pretty severe memory leak since upgrading from p114 to
p287.  I ran valgrind on my test suite and got this error:

==24626== 352 (48 direct, 304 indirect) bytes in 2 blocks are definitely
lost in loss record 13 of 56
==24626==    at 0x4A19DDB: malloc (vg_replace_malloc.c:207)
==24626==    by 0x42CFE3: ruby_xmalloc (gc.c:110)

==24626==    by 0x414F57: rb_eval (eval.c:3484)

Sorry I can't decipher the output very well.  Can anyone else figure out
the stack and what this means?  I would be happy to get more detail,
just let me know what you need.
