The added test case fails with a doulbe fault, which appears to be
caused by a stack overflow in the code that tries to handle the stack
overflow. So bumping it to 4096 bytes should give the code enough stack
space to play with.
If we got here from memory_protection_error(), then the stack pointer
has been fiddled with and the elements of these vectors, which address
stack-allocated objects, are bogus and needs to be resetted.
clang-format doesn't recognize casts to non-pointer/non-template types
so it winds up adding a space between the right paren and the expression
and then failing to recognize prefix operators in the process
(e.g. foo = (cell) & bar; should be foo = (cell)&bar;). This commit
manually fixes up the major cases (fixnum, cell, all types ending in _t).
Factor is finally a real C++ project and has a custom assert macro. Assertion failures were still getting caught as exceptions and causing failure loops. Write our own macro that calls factor::abort on failure.
This makes the separate "code" and "entry_point" fields in word and quotation redundant, so also remove them to reclaim an additional cell per word and quotation object, which should help with #318.
