+I have attached a modified version of racy to demonstrate my bug.
+
+Here's the error:
+*** glibc detected *** ./racy: double free or corruption (fasttop):
+0x0808a5c8 ***
+
+Here's my backtrace:
+======= Backtrace: =========
+/lib/libc.so.6[0xb7bfab11]
+/lib/libc.so.6(__libc_free+0x89)[0xb7bfb5e9]

+/lib/libpthread.so.0[0xb7d5d604]
+/lib/libc.so.6(__clone+0x5e)[0xb7c51cde]
+
+I am unable to upgrade easily atm because gentoo still has an old
+version.  If you are unable to trigger the bug on your system then I
+will upgrade...
