Failed to create thread (fedora only) #24

Open eserte opened 4 years ago

eserte commented 4 years ago

t/basic.t fails on my fedora 31 smokers (perls compiled without threads, if that matters). No errors on my other systems (centos, debian, ubuntu, freebsd):

Failed to create thread: No such file or directory (2) at /home/cpansand/.cpan/build/2020031700/Kafka-Librd-0.15-1/blib/lib/Kafka/Librd.pm line 66.
t/basic.t ...... 
Dubious, test returned 2 (wstat 512, 0x200)
No subtests run

(And probably $! isn't set here, the error message looks dubious)

Sometimes the failure comes together with a segmentation fault:

Sometimes also the message

is printed.

Do you know if Alien::Librdkafka did a system or share install? if system what version?

If a share install: I just bumped the version used for a share install, might be interesting to see if it works on the previous version (1.03_01 uses the older version of librdkafka), if nothing else to rule it out as a problem.

Librd.so uses /lib64/librdkafka.so.1, which comes from the RPM package librdkafka-0.11.6-3.fc31.x86_64
