Summary: stdlibc++ fails putting a double in a stream.
Description:
The problem was:
putting a double in a stream:
cout << 10.5 ;
Produce an empty string, or some garbage characters.
I could resolve the error down to some wired Code combination between
uclibc and libstdc++

I don't think it's an buildroot Problem.
Its an uclibc c++ error...

New info.
The Problem is: very old files are patched into current gcc releases.
I mean the toolchain/gcc/4.2.1/200-uclibc-locale.patch
which creates
gcc/libstdc++-v3/config/locale/uclibc/c_locale.cc
The file created by the patch is based on the generic Config and than
patched for uclibc. But the generic is changed with 4.x.x.
Best solution would be to copy the gcc/libstdc++-v3/config/locale/generic
Dir and than add a patch on this Dir.
The Differences needed would be smaller. And perhaps the Patch would work
for multiple gcc versions.

The Patch gcc_snprintf_double_cssize.patch is a workaround, hacking the
change in gcc. But it isnt a good solution.

I've been bitten by this as well. IMHO the proper solution is to mimic
non-C99 behaviour so convert_from_v should use sprintf instead of snprintf
when the size is 0. I attached the modified c_locale.h file.

Hello all,
I have hit this old bug with a toolchain for ARM based on gcc-4.0.3 and
uclibc-0.9.28. The issue is described below and in the thread of the bug
there seems to be a couple of patches that fixes the problem:
> gcc_snprintf_double_cssize.patch
> c_locale.h
I am trying to get those patches, but the bug-tracking system seems not
to have bug #1090. I seem to remember some changes in the buildroot
servers lately, so that might be the reason why i cannot reach older bugs.
Does anyone here still have those patches?
Someone with access to the old bug's database that can take those
patches and send them to the list or to my e-mail (below)?
Thanks in advance.

Yes, the old bugtracker is gone and we have a bugzilla installation
instead.
Javier> Does anyone here still have those patches?
Sorry, not me.
