Some code segfaults on compiling.

[magnetophon]

The exact error is:

/nix/store/b3jajrfg8hyy0nz7m22fdri9wb2w1jbm-faust2lv2-2016-07-19/bin/.faust2lv2-wrapped: line 363:  9414 Segmentation fault      "$tmpdir/$clsname" > "$tmpdir/$lv2name/$clsname.ttl"

Steps to reproduce:

git clone https://github.com/magnetophon/faustCompressors.git
cd faustCompressors
faust2lv2 -time -double -vec -gui RMS_FBcompressor_peak_limiter.dsp

Compiles just fine. Then do:

sed -i "s|15|16|" "compressors.lib"
faust2lv2 -time -double -vec -gui RMS_FBcompressor_peak_limiter.dsp

and get the error. The sed line only affects this line.

Another affected dsp is RhythmDelay. Same error.

What the heck is .faust2lv2-wrapped? And what's at line 363 in that file?

[magnetophon]

It's just faust2lv2, adapted to NixOS. For context, in case the NixOS adaptions have changed line numbers, here's line 358 till 363:

# This compiles the plugin to an executable which is run to generate the
# plugin-specific part of the manifest.
$CXX $CXXFLAGS -DDLLEXT="\"$dllext\"" $FAUSTTOOLSFLAGS $CPPFLAGS "$tmpdir/$cppname" -o "$tmpdir/$clsname" || exit 1
"$tmpdir/$clsname" > "$tmpdir/$lv2name/$clsname.ttl"
rm -f "$tmpdir/$clsname"
fi

Ok, I can reproduce the error. Not sure what's happening there, will have a look asap.

Compiles fine with the latest Faust (2.0.a58) for me, also runs fine in Ardour, so whatever the issue was, it seems to be fixed upstream.

@magnetophon, if this issue still persists for you, feel free to reopen it, but at least the test witness you provided here works all right for me now, even with rmsMaxSize = 2:pow(19).
