I'm currently testing the latest CVS, but with these changes rolled back:
Thus far, I have not yet seen the crash. I'll hammer on it more to make
BTW, that stack trace's addresses correspond to:
Which is unsurprising and also not very informative (I'd already found
where the fatal error was coming from by searching for "could not load"
in the sources).
When looking at the autoload.cc code, I noticed the api_fatal call is
still using dll->name as an ascii string when revision 1.171 changed
dll->name to a wide string. That's why the error message only prints the
first character of the dll name.
