Audacity crashes during spectrum building

Audacity Help Forum GNU/Linux

I am running Audacity 2.0.5 (downloaded from repositories) on Linux Mint 17.2 (Linux version 3.16.0-38-generic (buildd@aatxe) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #52~14.04.1-Ubuntu)

I have just tried to import Raw Data and look at its spectrum but Audacity crashed with a segmentation fault. No error messages are generated by Audacity.
How to reproduce:

  1. Launch Audacity;
  2. File → Import → Raw Data…;
  3. Choose the attached file “BUG CAUSING VERY DANGEROUS NEVER LOOK AT THE SPECTRUM BLYAD”;
  4. Choose the following options:
  • Encoding: 64 bit float;
    • Byte order: Big-endian;
    • Channels: 1 Channel;
    • Start offset: 0 bytes;
    • Amount to import: 100 %;
    • Sample rate: 44100 Hz;
  1. Try to look at the spectrogram.
  2. ???
  3. Segmentation fault!

You can see the output in the attached files.

I’m using Audacity 2.1.2 rc1 on Debian stable with XFCE desktop.
No segmentation fault, no crash, but the imported file is garbage with those settings.

Import with the detected settings:

  • Encoding: 64 bit float;
  • Byte order: Little-endian;
  • Channels: 2 Channels (stereo);
  • Start offset: 0 bytes;
  • Amount to import: 100 %;
  • Sample rate: 44100 Hz;

and I get a stereo track with an 880 Hz sine wave.

We can’t fix any bugs in obsolete versions of Audacity. You could uninstall 2.0.5 and try the “Ubuntu Handbook” 2.1.1 PPA from https://launchpad.net/~ubuntuhandbook1/+archive/ubuntu/audacity.
