Ok, not .mem then. How did you build boost for emscripten? Perhaps the problem lies there. Or are you only using header portions of boost?
Also possible boost has undefined behavior somewhere that LLVM is exploiting. Narrowing it down within boost would help. Is that latest boost? If not, might have bugs that were fixed meanwhile. - Alon On Wed, Mar 25, 2015 at 4:16 PM, <[email protected]> wrote: > But if I change the program to the below (i.e. replace boost stuff with > vector), then it works fine even with O3 optimisation, so would it really > have to do with the mem file (since if this is the case, then it should > also afflict the vector case below)? : > > #include <iostream> > #include <boost/shared_ptr.hpp> > #include <vector> > using namespace std; > > extern "C" { > double test(void) { > //boost::shared_ptr<int> y = boost::shared_ptr<int>(new int(42)); > //return *y; > vector<int> y; > y.push_back(333555); > return y[0]; > } > } > > > > On Wednesday, March 25, 2015 at 11:04:50 PM UTC, Alon Zakai wrote: >> >> file:// urls might hide failed loads.
