perf stat: fix NULL pointer reference bug with event unit This patch fixes a problem with the handling of the newly introduced optional event unit. The following cmdline caused a segfault: $ perf stat -e cpu/event-0x3c/ ls This patch fixes the problem with the default setting for alias->unit which was eventually causing the segfault.
