test_core segfaults #8

Closed nickoe closed 2 years ago

nickoe commented 2 years ago

Hi

I just wanted to try this out and was just mucking around. I noticed that the check package is noted optional as currently mentioned in the readme, but cmake requires it when configuring -- so I just installed it and I built it all successfully.

Because I installed check I just tried to run the test binaries, but test_core segfaults for me:

Running with with valgrind as the run_tests.sh script does I get an error in the error summary as well:

Can you paste full valgrind output? CI shows no errors: https://app.travis-ci.com/github/dernasherbrezon/sdr-server/jobs/546370841

@dernasherbrezon Sure. Here is the output from valgrind:

segfault is in pthread, which is coming from libpthread-2.33.so. I found this version only in Ubuntu 21.04. And I cannot reproduce it there:

What operation system are you using? Is it 100% reproducible?

nickoe commented 2 years ago

Sorry for the delay in response, but yes, it is 100% reproducible. I am using Archlinux on my workstation, I also tried it on my laptop with archlinux as well. test_core also segfaults with the same backtrace in gdb.

I am not sure if the verison of lib rtl sdr is important, but I have local/rtl-sdr-git 1:0.6.0.r32.gd770add-1

dernasherbrezon commented 2 years ago

Yes, I was able to reproduce this on Archlinux. It looks like something to do with glibc version. I will investigate further.

nickoe commented 2 years ago

I can confirm that your fix in 023ed2b552b783b5e8052dfc029812e9a256e48d appears to fix the segfault! :dancers:
