Hi Bruno,
In preparation for some libtool patches against Eric's reports, I
decided to upgrade my gnulib checkout and rebuild m4 HEAD against
it. I'm on the opposite side of the planet to my ppc machine for
the next few months, but there are /\(still\|new\)/ frexpl bugs in
gnulib on my intel MacBook:
$ VERBOSE=1 make check TESTS='test-frexpl test-printf-frexpl'
[[...]]
make check-TESTS
i:-16382 exp:-16384
../../../tests/gnu/test-frexpl.c:136: assertion failed

FAIL: test-printf-frexpl
===============================
2 of 2 tests failed
Please report to address@hidden
===============================
I added these printfs to the failing test sources to generate the
extra output:
tests/gnu/test-frexpl.c:135:fprintf(stderr, "i:%d exp:%d\n", i, exp);
tests/gnu/test-printf-frexpl.c:94:fprintf(stderr, "exp=%LA mantissa=$
%LA my_ldexp<=%LA\n", exp, mantissa, my_ldexp(1.0L, i - LDBL_MIN_EXP));
The mysteries of double precision representation in memory continue to
confound me, but if I can provide you with anything else to help fix
this, please let me know.
Cheers,
Gary
