Yes, but this does not seem to be a simple memory problem. I tested under
Solaris, and this works with fisher.test(T), and with fisher.test(T,
workspace=1e6) as well (with the default memory size). Under WinNT,
fisher.test(T, workspace=1e6) works fine. I did not suspect a memory
problem since the crash occurs only with _this_ sample but not with other
samples of similar size.
