<pre>The following invalid OpenMP code crashes clang when using `-fopenmp`
class S {
public:
operator int();
S& operator+=(int);
};
int main() {
S s1;
#pragma omp taskloop
for (S s = S(); s < s1; s += 1)
{}
}
Curiously `parallel for` does not fail so perhaps the observed crash is due to
something related to task constructs.
However both gcc and icc reject this loop (including the equivalent `[parallel
]for`) so it looks like clang should reject it too. My understanding is that
variables of class `S` are not random access iterators.
Kind regards,</pre>
