    copied!<p>Could someone explain to me why this:</p> <pre><code>unsigned char * buf; buf = new unsigned char[dataSize]; </code></pre> <p>is crashing my c++ program? It's not giving me any error's so I'm really lost as to the reason why my program is crashing due to these lines of code. Thank you in advance!</p> <p>EDIT: Here's the code for the project I'm currently working on, it's using OpenAL so you'll need it if you want to recompile the code.</p> <pre><code>#include &lt;cstdlib&gt; #include &lt;iostream&gt; #include &lt;Windows.h&gt; #include &lt;al.h&gt; #include &lt;alc.h&gt; #include &lt;vector&gt; using namespace std; class SoundSource { public: ALuint Source; ALuint buffer; ALuint frequency; ALenum format; //position ALfloat sourcePos[3]; ALfloat sourceVel[3]; }; ALCcontext * Context; ALCdevice * Device; SoundSource sound; int endWithError(char * msg, int error = 0) { cout &lt;&lt; msg &lt;&lt; endl; while(cin.get() != 10); return error; } bool initSound() { Device = alcOpenDevice((ALCchar*)"DirectSound3D"); if(Device == NULL) return false; else { Context = alcCreateContext(Device,NULL); alcMakeContextCurrent(Context); alGetError(); return true; } return false; } string loadSound(SoundSource s) { char type[4]; DWORD size, chunkSize; short formatType, channels; DWORD sampleRate, avgBytesPerSec; short bytesPerSample, bitsPerSample; DWORD dataSize; FILE * fp = NULL; fp = fopen("test.wav","rb"); fread(type, sizeof(char), 4, fp); if(!strcmp(type, "RIFF")) endWithError("Error: Not RIFF format"); fread(&amp;size, sizeof(DWORD), 1, fp); fread(type, sizeof(char), 4, fp); if(!strcmp(type, "WAVE")) endWithError("Error: Not WAVE format"); fread(type, sizeof(char), 4, fp); if(!strcmp(type, "fmt ")) endWithError("Error: Not fmt format"); fread(&amp;chunkSize, sizeof(DWORD), 1, fp); fread(&amp;formatType, sizeof(short), 1, fp); fread(&amp;channels, sizeof(short), 1, fp); fread(&amp;sampleRate, sizeof(DWORD), 1, fp); fread(&amp;avgBytesPerSec, sizeof(DWORD), 1, fp); fread(&amp;bytesPerSample, sizeof(short), 1, fp); fread(&amp;bitsPerSample, sizeof(short), 1, fp); cout &lt;&lt; "Chuck size: " &lt;&lt; chunkSize &lt;&lt; endl; cout &lt;&lt; "Format type: " &lt;&lt; formatType &lt;&lt; endl; cout &lt;&lt; "Channels: " &lt;&lt; channels &lt;&lt; endl; cout &lt;&lt; "Sample rate: " &lt;&lt; sampleRate &lt;&lt; endl; cout &lt;&lt; "Avg Bytes per sec: " &lt;&lt; avgBytesPerSec &lt;&lt; endl; cout &lt;&lt; "Bytes per sample: " &lt;&lt; bytesPerSample &lt;&lt; endl; cout &lt;&lt; "Bits per sample: " &lt;&lt; bitsPerSample &lt;&lt; endl; fread(type, sizeof(char), 4, fp); if(!strcmp(type, "data")) endWithError("Error: No data"); fread(&amp;dataSize, sizeof(DWORD), 1, fp); unsigned char * buf; buf = new unsigned char[dataSize]; fread(buf, sizeof(BYTE), dataSize, fp); alGenBuffers(1, &amp;s.buffer); alGenSources(1, &amp;s.Source); switch(bitsPerSample) { //8 bit case 8: { switch(channels) { case 1: s.format = AL_FORMAT_MONO8; break; case 2: s.format = AL_FORMAT_STEREO8; break; } } //16 bit case 16: { switch(channels) { case 1: s.format = AL_FORMAT_MONO16; break; case 2: s.format = AL_FORMAT_STEREO16; break; } } } alBufferData(s.buffer, s.format, (ALvoid *)buf, dataSize, s.frequency); s.sourcePos[0] = 0.0; s.sourcePos[1] = 0.0; s.sourcePos[2] = 0.0; s.sourceVel[0] = 0.0; s.sourceVel[1] = 0.0; s.sourceVel[2] = 0.0; fclose(fp); //delete[] buf; return "WAVE successfully loaded!"; } void closeSound() { alDeleteSources(1, &amp;sound.Source); alDeleteBuffers(1, &amp;sound.buffer); Context = alcGetCurrentContext(); Device = alcGetContextsDevice(Context); alcMakeContextCurrent(NULL); alcDestroyContext(Context); alcCloseDevice(Device); cout &lt;&lt; "OpenAL sound closed!" &lt;&lt; endl; } int main() { string result; if(initSound()) { cout &lt;&lt; "Sound Context and Device up!" &lt;&lt; endl; result = loadSound(sound); cout &lt;&lt; result.c_str() &lt;&lt; endl; alSourcePlay(sound.Source); system("PAUSE"); } else { { cout &lt;&lt; "Sound Context and Device not made.." &lt;&lt; endl; system("PAUSE"); } } closeSound(); return 0; } </code></pre>
