Hi Heiko.
Just a hunch... try editing t/10-run.t like this:
--- t/10-run.t (revision 1085)
+++ t/10-run.t (working copy)
@@ -11,7 +11,7 @@
use Devel::NYTProf::Run qw(profile_this);
run_test_group( {
- extra_options => { stmts => 0 }, # RT#50851
+ extra_options => { stmts => 0, compress => 0 }, # RT#50851
extra_test_count => 1,
extra_test_code => sub {
my ($profile, $env) = @_;
and let us know (ASAP please as this is the last issue holding up a
release).
If that does _not_ fix it then please:
1. install the module
2. set the NYTPROF env vat to "trace=99"
3. send me the output of:
nytprofhtml --file nytprof_10-run.out
Thanks.
Tim.
