Hello; using Fedora 19 x64, recent install, May 2013 2.0.3 from repos.
Both free and non-free Audacity segfault when using Equalization function; other functions appear to work.
Per other reports, I visually checked, removed swapped in known good /usr/share/audacity/EQDefaultCurves.xml. No change.
Strace shows little except for opening font files before SIGSEGV.
Thank You.
Looking further, I am adding this partial backtrace at the point of segfault…

Try building the latest 2.0.4 alpha development code http://audacityteam.org/community/developers#svn .
I sometimes got segfaults using Save/Manage Curves in EQ on Ubuntu until we fixed a bug in EQ sometime after 2.0.3 release.
If the current code has the same problem, please provide steps to reproduce and the complete backtrace (wrap it inside code tags using the button in the message edit window).

I can confirm segmentation faults occurring on:
Reproducer:
Start audacity
Generate|Sine| defaults 30 seconds long.
Effect|Equalizer
What happens:
audacity disappears.
when run from command prompt:
Program received signal SIGSEGV, Segmentation fault.

At this point, audacity is not playing/recording audio, so seems UI / processing related.
This does not happen with Audacity sources on Ubuntu.
Please try building Audacity from our source http://audacityteam.org/download/source .
We are not responsible for Fedora builds, so if their builds segfault but Audacity source doesn’t, then you must complain to Fedora. Have you looked at the Fedora bug tracker for other reports?
Gale
OK, thanks, I am much more interested if it occurs in the latest code.
Is your computer 64-bit, like the others?
Can you and others post your EQCurves.xml from ~/.audacity-data/ ?
Then I’ll try it on 64-bit Ubuntu with default curves and any others that are posted.
Gale
Hey Gale, it looks like Arch is not applying any patches that I (as one of the fedora/rpmfusion package maintainers) am using in the fedora package.
Bugs on Fedora:
https://bugzilla.redhat.com/show_bug.cgi?id=987837
https://bugzilla.redhat.com/show_bug.cgi?id=999145 captured by abrt with backtrace.
Biggest changes in fedora package appear to be: enabling libsoxr, using system portaudio, changes to use ffmpeg-compat. Do any of these interact with Equalizer effect ?
EQCurves.xml (4.54 KB)
I tried out a bunch of Fedora built Audacity builds on my x86_64 machine. The same rpm spec file, source and patches for 2.0.3 and 2.0.4 but built for Fedora 18 (previous release) and Fedora 19 (current release) can all be installed on Fedora 19. Only the ones built in Fedora 19’s or later build systems show this issue.
So, could be changes in includes especially wxGTK etc, or due to using a newer gcc compiler. I have asked on Fedora-devel list for info in case this raises eyebrows with someone more familiar with what might cause this.
Can non-fedora users seeing this issue (crash at Effect|Equalization) reply with the distribution, release, and the current wxGTK and GCC versions that the system is using ?
If you know which versions of wxGTK and GCC were included/used in the build process, that would be important as well, so please add that as well.
Hi,
Sorry I’ve had no time yet to check this on Ubuntu 64-bit, but does this recent code change prevent the crash http://code.google.com/p/audacity/source/detail?r=12569 ?
