Hello Chris, or anyone else affected, Accepted eglibc into precise-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/eglibc/2.15-0ubuntu10.12 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

With the following testcase, it happens while it shouldn't, according to
the manual:

printf(%d\n, snprintf(buf, 150, %.50s, STR));

}
-8---
The manual page has this to say:
About precision:
An optional precision, in the form of a period (#8216;.#8217;) followed by
an
optional decimal digit string.(...) This gives (...) the maximum
number of characters to be printed from a string for s and S
conversions.
About s:
If no l modifier is present: The const char * argument is expected to
be a pointer to an array of character type(...)
If an l modifier is present: The const wchar_t * argument is expected
to be a pointer to an array of wide characters. Wide characters from
the array are converted to multibyte characters (...)
There is no l modifier, but still, the string goes through the
multibyte conversion code, and fails because the string is invalid
multibyte.
Note, it only works with non UTF-8 locale set in LC_CTYPE or LC_ALL.
This is debian bug http://bugs.debian.org/208308

Here's a simpler testcase for this bug courtesy of Jonathan Nieder:
#include stdio.h
#include locale.h
int main(void)
{
int n;
setlocale(LC_CTYPE, );
n = printf(%.11s\n, Author: \277);
perror(printf);
fprintf(stderr, return value: %d\n, n);
return 0;
}
Under a C locale that'll do the right thing:
$ LANG=C ./test
Author: #65533;
printf: Success
return value: 10
But not under a UTF-8 locale, since \277 isn't a valid UTF-8 sequence:
$ LANG=en_US.utf8 ./test
printf: Invalid or incomplete multibyte or wide character
return value: -1

This may be a duplicate of another longstanding bug report that Mr.
Drepper has marked as WONTFIX despite it being obviously non-conformant.
He seems to believe, for whatever reason, that avoiding writing out
incomplete multibyte sequences in incorrect programs that use %.NNs
formats haphazardly with multibyte strings is more important than not
breaking correct programs that are using %.NNs with strings not intended
to be interpreted as multibyte characters in the current locale. Neither
C nor POSIX makes any requirement that strings used with the %s format
specifier be valid multibyte character sequences in the current locale;
glibc is simply wrong on this issue.
