    Since b13 (last version I had previously installed was b11) I get the errors below when running a webgl build. It happens in all compile modes (fast, fastest, slow), right on startup. I found it in a project that mostly worked (with some other issues) in b11.

    In release builds this is the error:
    Code (CSharp):
    1. exception thrown: InternalError: too much recursion
    Switching to development build the log looks a bit more useful:
    Code (CSharp):
    1. "warning: a problem occurred in builtin C++ name demangling; build with  -s DEMANGLE_SUPPORT=1  to link in libcxxabi demangling" localhost:8888:63
    2. Module.printErr() localhost:8888:63
    3. Runtime.warnOnce() webgl-slow-dev.js:318

    10. __ZN15FileSystemEntryC2EPKc() webgl-slow-dev.js:1516683
    11. __Z18IsDirectoryCreatedRKNSt3__112basic_stringIcNS_11char_traitsIcEENS_9allocatorIcEEEE() webgl-slow-dev.js:1523160

    the last line here repeats many times until the recursion limit is reached (I assume).

    I'm not sure what it means, but it seems to be related to creating directories. But I'm not accessing any files or creating directories.

    Could you report a bug with a repro case on this?
