The fact that it is related to key bindings is not too strange, since
the crash occurs in key-handling code. What is very strange, though,
is the following

See ho "encoding" has a reasonable-looking address in #1, but is @0x0
in #0. This does not seems possible according to the code for
getISOEncoded:
char QLyXKeySym::getISOEncoded(string const & encoding) const
{
if (lyxerr.debugging())
lyxerr[Debug::KEY] << "encoding is " << encoding << endl;
unsigned char const c = encode(encoding, text_);
if (lyxerr.debugging())
lyxerr[Debug::KEY] << "ISOEncoded returning value " << int
(c) << endl;
return c;
}
As you see, the variable "encoding" (which is constant anyway) is
passed unchanged.
Could this be a compiler bug? I guess you have the latest updates.
I do.
Could you try to compile without optimization
(--disable-optimization).
I still get a crash:
Program received signal EXC_BAD_ACCESS, Could not access memory.
