Subject: [Bug libc/4977] SEGV in strlen() of string argument of vsnprintf call on RHEL WS3/64-bit
Date: Wed, 29 Aug 2007 16:41:00 -0000	[thread overview]
Message-ID: <20070829164055.12315.qmail@sourceware.org> (raw)
In-Reply-To: <20070829152853.4977.timp@pulsic.com>


------- Additional Comments From jakub at redhat dot com  2007-08-29 16:40 -------
Last note:
Each invocation of the va_start() and va_copy() macros shall be matched by a
corresponding invocation of the va_end() macro in the same function.
just to be sure.
The current va_end() is fine, all you need to add
va_list ap2;
va_copy (ap2, ap);
before the first vsnprintf call, change second (or first, doesn't matter which
one if just one) vsnprintf call to use ap2 instead and add
va_end (ap2);
after that call.
