Aborted (core dumped).

The code is working good in windows 10. But i am trying to run this in my Ubuntu 20.04 LTS x64. Each time i run it gives me this error

free(): invalid pointer
Aborted (core dumped)

Can anyone explain to me why this is happening. I also installed the c++ build tools as well and i am using python 3.7.0 in a conda virtual environment. I

ran the setup.py file with different commands like easy_install, install, build etc but i cannot figure out the error. please let me know if you need more details from me.

There's another error occur when i ran the python test_microphone.py

Fatal error: glibc detected an invalid stdio handle
Aborted (core dumped)

What is the full output before crash

[Nouman945]

Here this is the output right now. I also showed the packages versions i am using.

[nshmyrev]

Ok, what is the output of test_simple.py?

[Nouman945]

Its working for the test_simple.py test.wav

but the same error for test_microphone.py

Segmentation fault (core dumped)

[nshmyrev]

It should be the crash of sounddevice then, probably something with portaudio. What is the OS exactly, portaudio version on your system.

It also helps to collect backtrace like this:

gdb --args python3 ./test_microphone.py

then "run", when it crashes "backtrace".

[Nouman945]

I am using

• Ubuntu 22.04 LTS
• PyAudio==0.2.11
• python==3.7.0

[Nouman945]

Yes tracked the error. but cannot understand it. its not giving the full path so i can put the file there.

Backtrace.

[nshmyrev]

Hm, looks strange. Does plain sounddevice example

https://github.com/spatialaudio/python-sounddevice/blob/0.4.4/examples/rec_unlimited.py

work for you without crashes?

[Nouman945]

Yes its working without any crash.

[Nouman945]

Other files are working fine the crash is with only test_microphone.py file. I tried with different versions of python as well but its the same error

[nshmyrev]

On the screenshot above you try to run gdb in base environment but rec_unlimited in the nlp environment. Can you try to run them in the same environment? Or, even better, can you check if it works with system python without conda?

[Nouman945]

I got it working. thank you so much for guiding man !! I case anyone have the problems installing Pyaudio in Ubuntu you can use

$ sudo apt-get install portaudio19-dev python-all-dev
$ pip3 install pyaudio

I got it working with python 3.10

[nshmyrev]

This is wrong. Our samples do not use pyaudio at all, we use sounddevice.

[Nouman945]

It was required to run the test_microphone.py file. But after i installed this it started working

@Nouman945 solution also worked for me, thanks.
