_M_extract_buffer_length = 32

[k]

In the "double" overloaded version of do_get()  (buried inside
i686-pc-linux-gnu/libstdc++-v3/include/bits/locale_facets.tcc), the comment
makes reference to "the size of 256" (line 595 for 3.0.3), but
the array __xtrc is declared to be of length 32 (i.e.,
_M_extract_buffer_length).  This is probably a bug.
My problem is trying to get this bit of code to work:
double x; cin >> x;
and I input "0.12345678901234567890123456789012345678901234567"
Anything more than 30 digits past the decimal point
breaks.  I want it to gracefully round or truncate.
Suggestions?
Thanks,
Ken Takusagawa
