Segmentation Fault #44

Open guicontat opened 9 years ago

guicontat commented 9 years ago

Hello,

My code :

var coreAudio = require("node-core-audio") , SegfaultHandler = require('segfault-handler') ;

SegfaultHandler.registerHandler(); var engine = coreAudio.createNewAudioEngine();

function processAudio( inputBuffer ) {
return inputBuffer[0][0]; }

engine.addAudioCallback( processAudio );

does a Segmentation Fault.

Here is the stacktrace

PID 7906 received SIGSEGV for address: 0x20 /home/guicontat/live_sound/node_modules/segfault-handler/build/Release/segfault-handler.node(+0x1175)[0x7fe452383175] /lib/x86_64-linux-gnu/libpthread.so.0(+0x10340)[0x7fe453564340] /home/guicontat/live_sound/node_modules/node-core-audio/build/Release/NodeCoreAudio.node(_ZN5Audio11AudioEngine12applyOptionsEN2v85LocalINS1_6ObjectEEE+0x1de)[0x7fe45017a6ee] /home/guicontat/live_sound/node_modules/node-core-audio/build/Release/NodeCoreAudio.node(_ZN5Audio11AudioEngineC1EN2v85LocalINS1_6ObjectEEE+0x1c5)[0x7fe45017ad95] /home/guicontat/live_sound/node_modules/node-core-audio/build/Release/NodeCoreAudio.node(_ZN5Audio11AudioEngine3NewERKN2v820FunctionCallbackInfoINS1_5ValueEEE+0x71)[0x7fe45017b141] node(_ZN2v88internal25FunctionCallbackArguments4CallEPFvRKNS_20FunctionCallbackInfoINS_5ValueEEEE+0x92)[0x7b8e02] node[0x7d87d0] [0x28af33d0740e]

The Segfault is cause by

line 214 in AudioEngine.cpp

m_inputParams.suggestedLatency = Pa_GetDeviceInfo(m_inputParams.device)->defaultLowInputLatency;

and line 220

m_outputParams.suggestedLatency = Pa_GetDeviceInfo(m_outputParams.device)->defaultLowOutputLatency; Do you know how can i fix it ?
