| Subject: | Test failures in quadmath/threading builds of 5.24 and 5.25 |
Hello:
While performing smoketesting of CPAN modules using perl 5.24.0 through bleadperl, I noticed that tests for Math::Prime::Util seemed to hang. The relevant parts of my config are that this is a -DDEBUGGING perl, with quadmath, threads, and multiplicity. Full -V and test reports are attached. After the panic in t/31-threading, the test suite hangs and needs to be killed. Failures:
Appears only in 5.25.0:
t/11-primes.t ................ 1/124 Negative repeat count does nothing at /home/dcollins/.cpan/build/Math-Prime-Util-0.58-dY84ZQ/blib/lib/Math/Prime/Util/PP.pm line 413.
Negative repeat count does nothing at /home/dcollins/.cpan/build/Math-Prime-Util-0.58-dY84ZQ/blib/lib/Math/Prime/Util/PP.pm line 413.
# Failed test 'primes(inf,inf)'
# at t/11-primes.t line 40.
# Looks like you failed 1 test of 124.
t/11-primes.t ................ Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/124 subtests
Appears in all 5.24 and 5.25 series releases:
t/28-pi.t .................... 1/4
# Failed test 'Pi(0) gives floating point pi'
# at t/28-pi.t line 22.

# Failed test 'Pi(2 .. 50)'
# at t/28-pi.t line 25.
# Structures begin differing at:

# Looks like you failed 2 tests of 4.
t/28-pi.t .................... Dubious, test returned 2 (wstat 512, 0x200)
Failed 2/4 subtests
Appears in all 5.24 and 5.25 series releases, and hangs immediately after printing this output:
t/31-threading.t ............. 2/10 Thread 13 terminated abnormally: panic: free from wrong pool, 130c010!=25cfab0 at t/31-threading.t line 82.
Use of uninitialized value in addition (+) at t/31-threading.t line 131.
Perl -V and buildlogs attached. 5.24.0 looks just like 5.25.3.
Math::MPFR is also failing on this platform, but since it is marked "optional", CPAN is still willing to test Math::Prime::Util. Unfortunately, CPAN::Testers reports aren't being sent due to the hanging test.
