c++.stl.sgi - hang with full optimization (SGI STL 3.3/dmc 8.27)
- Marcus Elderic Koenig (38/38) May 21 2002 Hi there,
- Walter (4/34) May 21 2002 At the moment, there is no resolution for it, although you can try 8.28 ...
Hi there,
can anyone tell me why programs compiled with -o keep
hanging, if I use template set<>:
-SNIP-
set<float> floatcache;
float x, y, z;
vector<string>::iterator vecPos;
if (temp.size() > 0) {
cout << "scanning for floats... " << endl;
for (vecPos = temp.begin();
vecPos != temp.end();
vecPos++) {
if (sscanf(vecPos->c_str(), "v %f %f %f", &x, &y, &z) == 3) {
floatcache.insert(x);
floatcache.insert(y);
floatcache.insert(z);
};
};
};
-SNIP-
--------------------------------------
if I compile this program without -o,
it runs just fine and inserts all the scanned floats
into the set.
compiler: digitalmars 8.27 / SGI STL 3.3
I downloaded the SGI STL 3.2 from the homepage earlier...
in the sample code for set<>, there's a #pragma message
saying "JAK! full optimization causes hang!".
This seems to be a know bug. Is there a solution for it?

At the moment, there is no resolution for it, although you can try 8.28 out
on it. Also, it may not be hanging, it just may be taking a long time.
