Comment 10 for bug 810214

I got the craziest crash happening on sparc linux, when running xpcshell with jemalloc enabled, it crashes in "setbuf(stdout, 0);" (which is a libc function).

It turns out this is due to the fact that the _IO_stdin_used symbol is not exported, because of the version script used to hide most symbols from programs. No idea why this only crashes on sparc, though.
