That 1MB allocation must have just pushed it over the top of the total memory usage exceeding 16MB.
If you see a difference between two browsers here, it is likely either a browser bug or a timing-related issue, as running out of memory in emscripten is managed entirely by emscripten (we just allocate a typed array and handle allocations inside it ourselves), not by the JS engine. In other words, the browser's memory management should not matter. If you can consistently reproduce the problem and can share a testcase, please file a bug. - Alon On Mon, Feb 16, 2015 at 6:34 PM, Ishaan Venkatesan < [email protected]> wrote: > Today I ran into the following exception after allocating an > std::vector<char> of size 718924 in C++.
