The head of the gomp branch reports an ICE when trying to compile the snippet
below:
template<typename T> struct Healpix_Map {
T *map;
int npix_;
void Import_nograde (const Healpix_Map<T> &orig) {
#pragma omp parallel
{
int m;
#pragma omp for schedule (dynamic)
for (m=0; m<npix_; ++m) map[m] = orig.map[m];
}
}
};
void foo(Healpix_Map<int> &a, Healpix_Map<int> &b) {
a.Import_nograde(b);
}
