bool CCTextureAtlas::initWithTexture(CCTexture2D texture, unsigned int capacity)
{
assert;
m_uCapacity = capacity;
m_uTotalQuads = 0;
// retained in property
this->m_pTexture = texture;
CC_SAFE_RETAIN;
m_pQuads = calloc m_uCapacity, 1 );
m_pIndices = (GLushort )calloc m_uCapacity * 6, 1 );

if( ! ( m_pQuads && m_pIndices) ) {
//CCLOG(“cocos2d: CCTextureAtlas: not enough memory”);
CC_SAFE_FREE(m_pQuads)
CC_SAFE_FREE(m_pIndices)
return false;
}

When the condition in if sentence is true, should release the texture. Because the destructure will release it, so should use CC_SAFE_RELEASE_NULL() to release it.
