Hi All,
On the NonStop platform, the entire test for t0211-trace2-perf.sh does not
work. The first case, in verbose, reports:
We get errors when the script is run:
Use of uninitialized value within @tokens in pattern match (m//) at

Our perl is v5.24.0 and this cannot be upgraded.
Thoughts?

Could you intrument that test top "cat" the raw trace.perf you get?
That's some bug in the perl side of the parsing.
But the real bug looks like the trace2 code unconditionally depending on
pthreads, even though NonStop has 'NO_PTHREADS = UnfortunatelyYes'
defined.
That's why we get this th%d:unknown stuff, the trace2/tr2_tls.c code
using pthreads is failing with whatever pthread-bizarro NonStop has.
That seems easy enough to "fix", just always fake up "main" if we don't
have pthreads, but perhaps Jeff H. has another opinion on it...

That's not NonStop. thread-utils.h (re)defines pthread_getspecific()
to return NULL when NO_PTHREADS, which triggers this I think.

The platform *is* NonStop, which has SPT and PUT pthreads, but we have never been able to make them work with git, so did not include them in the configuration.

I just reproduced this on my Mac with NO_PTHREADS defined.
I'll post a fix shortly.
