OK, then the bug is in gnulib's tests, not in glibc. Thanks for these tests.
I'm applying this:
2007-09-16 Bruno Haible <[EMAIL PROTECTED]>
* m4/printf.m4 (gl_PRINTF_LONG_DOUBLE, gl_PRINTF_INFINITE,
gl_PRINTF_INFINITE_LONG_DOUBLE): Increase buf's size from 100 to 10000.
Needed on glibc-2.6.1 with -fstack-protector -D_FORTIFY_SOURCE=2.
Reported by Greg Schafer <[EMAIL PROTECTED]>.
