Converting those last bytes to a string gives "ght_direction\x00:\x00\x00\x00\x00\x00\x00\x00slices\x00\x00d". There isn't anything in emscripten, LLVM or clang with the characters "ght_direction". Perhaps look for where that is in your codebase? Might be you have a function with non-unicode characters in its name or in a parameter name, and somehow clang and LLVM preserve that oddness when compiling.
Another odd possibility is somehow emscripten.py (the file that crashes) got corrupted somehow, and contains a non-ascii character in the text processing right before that crash? Using a new copy of emscripten could rule that out. - Alon On Wed, Oct 29, 2014 at 11:02 AM, Robert Goulet <[email protected]> wrote: > Cool that worked. > > It prints 16,1 for 234335:234339 > > It seems the offending character is the comma? > > There I printed 234300:234400 and I get: > > > 103,104,116,95,100,105,114,101,99,116,105,111,110,0,58,0,0,0,0,0,0,0,115,108,105,99,101,115,0,0,100, > > I really don't see what is wrong with these characters... encoding with > utf-8 doesn't change the print output. > > > > On Wednesday, October 29, 2014 1:12:09 PM UTC-4, Bruce Mitchener wrote: >> >> I am half asleep but maybe: >> >> print >> sys.stderr, mem_init... >> >> http://stackoverflow.com/questions/5574702/how-to- >> print-to-stderr-in-python >> >> - Bruce >> >> Sent from my iPhone >> >> On Oct 30, 2014, at 12:05 AM, Robert Goulet <[email protected]> >> wrote: >> >> Ok I added the try/except block and I think it went into the except part >> but I can't see it; the print function does not write into the Visual >> Studio output window.
