Subject: [mprof-report] Don't print a thread with a zero thread ID in the summary.
X-Git-Url: http://wien.tomnetworks.com/gitweb/?a=commitdiff_plain;h=f92d9d06745ff1ebadf55e6279add657744bef21;p=mono.git

[mprof-report] Don't print a thread with a zero thread ID in the summary.

Log buffers can end up with a zero thread ID when we synthesize events on the
writer thread, leading to mprof-report thinking a thread exists with that ID.
We simply ignore the "zero thread" in the thread summary.
