I can't reproduce this. The NYTProf.xs code has logic to save and
restore errno around the entry points to/from perl. I tried adding
code in FileHandle.xs to explicitly set errno in all the i/o functions
but still couldn't get test failures (unless I also disabled the errno
save/restore logic). I tried with and without zlib. r1166.
Is it reliably repeatable for you?
To help me narrow down the cause please try the following changes:
- edit t/50-errno.t to delete everything after line 31.
- change the test count from 8 to 4
- rerun to check it fails the same way
- rerun with each of the following changes to $ENV{NYTPROF} (line 6):
"start=init:file=$nytprof_out:blocks=0:stmts=0"
"start=init:file=$nytprof_out:blocks=0:subs=0"
"start=init:file=$nytprof_out:blocks=0:stmts=0:subs=0"
- also send me (off-list) the log from running whichever is the last of
those which fails, but with ":trace=90" appended to it.
Thanks!
Tim.
