Package: lv2file
Version: 0.95-2
When using lv2file to apply certain plugins, lv2file crashes with a
segmentation fault.
The common factor seems to be that plugins supporting the feature
http://lv2plug.in/ns/ext/worker#schedule trigger the crash. This is
consistent with the backtrace below, which shows that the crash happens
while parsing supported features.
Example:
# Create an input file. Details aren't important
$ sox -n -c 2 -b 16 -r 44100 input.wav synth 1 sine
# Apply the Dragonfly hall reverb plugin (from Debian package
dragonfly-reverb-lv2) to the input file
$ lv2file -i input.wav -o output.wav
https://github.com/michaelwillis/dragonfly-reverb
Note: Running 1 instances of the plugin.
Note: Mapping audio channels to plugin ports based on ordering
Segmentation fault
Same example with gbd backtrace, using symbols from lv2file-dbgsym and
dragonfly-reverb-lv2-dbgsym:
(gdb) run
Starting program: /usr/bin/lv2file -i input.wav -o output.wav
https://github.com/michaelwillis/dragonfly-reverb
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Note: Running 1 instances of the plugin.
Note: Mapping audio channels to plugin ports based on ordering
Program received signal SIGSEGV, Segmentation fault.

#3 0x0000555555557c23 in main (argc=<optimized out>, argv=<optimized
out>) at ./lv2file.c:785
(gdb)
The crash can be reproduced with many plugins from the Debian packages
guitarix-lv2 and lsp-plugins-lv2. Any plugin that lists
http://lv2plug.in/ns/ext/worker#schedule as a required or supported
feature seems to trigger the crash. On the other hand, plugins that
don't list that feature don't trigger the crash. For example, in the
dragonfly-reverb-lv2 package, urn:dragonfly:early doesn't crash, but
urn:dragonfly:plate and urn:dragonfly:room both crash with similar
backtraces to the one given above.
Thanks for maintaining this package!
Cheers,
Michael
