I know the Metrowerks library inside/out. I started looking at this
last night but I'm pretty lost in the test code.
Here's what I have so far:
Failure inside of:
template<typename Stream, typename String>
static void stream_extractor(Bitset& b,
BOOST_CHECK(remainder == str.substr(after_digits));
At this point remainder is a zero-length string, after_digits is 0 and
str is length 359.
On entry to this routine b has length 1 and that element is true. I
believe, but I am not positive that str is unmodified through this
test, despite being passed by reference (as opposed to const ref).
I've so far been unable to determine the state of the stream is on
entry. But it looks completely hosed by the time the BOOST_CHECK is
triggered. For example the iostate has the value 0x7E even though the
highest numerical state it can possibly have is 0x07.
did_throw is false.
