--- Comment #3 from Dmitry Kazakov <dimul...@gmail.com> ---
The backtrace actually points to this piece of code:
template <typename T>
T *value(QOpenGLContext *context) {
QOpenGLContextGroup *group = context->shareGroup();
// Have to use our own mutex here, not the group's, since
// m_groups has to be protected too against any concurrent access.
QMutexLocker locker(&m_mutex);
T *resource = static_cast<T *>(group->d_func()->m_resources.value(this,
0));
if (!resource) {
resource = new T(context);
insert(context, resource);
}
return resource;
}
It tries to dereference a pointer with value 0x08, which basically means that
either `context` is null or its shared group (`group`) is null. I don't know
why it could happen, but it does not look like it is a OOM issue.
