espresso:~/daily/gnulib/dummy-0/gltests jas$ ./test-ldexpl
test-ldexpl.c:99: assertion failed
Abort trap
espresso:~/daily/gnulib/dummy-0/gltests jas$
The code reads:
x = 1.73205L;
y = ldexpl (x, 0); ASSERT (y == x);
Printing the values yield:
x 1.732050 y -0.000000
I guess the Mac OS X 10.4 ldexpl implementation doesn't handle zero
exponents properly?
