Description: I have a piece of code which may result in underflows. I enclose the code in between fenv_t env; feholdexcept(&env); ... fesetenv(&env); Now the code in [...] is reading floating point numbers which may be very small and result in underflow floating point signals. However, since we have used feholdexcept() the signals should not be produced. And indeed they are not, until we reach fesetenv() where the signal is raised. If you read the manual of LIBC for fesetenv() The fesetenv function restores the floating point environ- ment from the object *envp. This object must be known to be valid, e.g., the result of a call to fegetenv or feholdexcept or equal to FE_DFL_ENV. This call does not raise exceptions. it says no exception should be raised. --------------------------------------- Received: (at 339318-done) by bugs.debian.org; 20 Dec 2005 01:30:14 +0000 >From [EMAIL PROTECTED] Mon Dec 19 17:30:14 2005 Return-path: <[EMAIL PROTECTED]> Received: from omega.webmasters.gr.jp ([218.44.239.78] helo=webmasters.gr.jp) by spohr.debian.org with esmtp (Exim 4.50) id 1EoWKU-0000gW-Mp for [EMAIL PROTECTED]; Mon, 19 Dec 2005 17:30:14 -0800 Received: from omega.webmasters.gr.jp (localhost [127.0.0.1]) by webmasters.gr.jp (Postfix) with ESMTP id EF47DDEB1B; Tue, 20 Dec 2005 10:30:13 +0900 (JST) Date: Tue, 20 Dec 2005 10:30:13 +0900 Message-ID: <[EMAIL PROTECTED]> From: GOTO Masanori <[EMAIL PROTECTED]> To: Juan Jose Garcia Ripoll <[EMAIL PROTECTED]>, Daniel Jacobowitz <[EMAIL PROTECTED]>, [EMAIL PROTECTED] Subject: Re: Bug#339318: Bug in fesetenv() [LIBC6.1] In-Reply-To: <[EMAIL PROTECTED]> References: <[EMAIL PROTECTED]> <[EMAIL PROTECTED]> User-Agent: Wanderlust/2.11.30 (Wonderwall) SEMI/1.14.6 (Maruoka) FLIM/1.14.6 (Marutamachi) APEL/10.6 Emacs/21.4 (i386-pc-linux-gnu) MULE/5.0 (SAKAKI) MIME-Version: 1.0 (generated by SEMI 1.14.6 - "Maruoka") Content-Type: text/plain; charset=US-ASCII X-Spam-Checker-Version: SpamAssassin 2.60-bugs.debian.org_2005_01_02 (1.212-2003-09-23-exp) on spohr.debian.org X-Spam-Level: X-Spam-Status: No, hits=-6.0 required=4.0 tests=BAYES_00,HAS_BUG_NUMBER autolearn=no version=2.60-bugs.debian.org_2005_01_02 At Sun, 20 Nov 2005 12:08:45 -0500, Daniel Jacobowitz wrote: > On Tue, Nov 15, 2005 at 02:49:57PM +0100, Juan Jose Garcia Ripoll wrote: > > Package: libc6.1 > > Version: 2.2.5-11.5 > > That's a very old glibc version.

I close this bug because there's no responce from the submitter. Juan, if you still see your bugs in the recent glibc version (ex: sarge or sid), please reopen this bug or just report it to us. It seems you run on ia64 or alpha - so it probably the actual bug, but we need to confirm the recent package has this kind of bugs in first. Note that it's nice idea to attach a sample code in your bug report because we hardly find what the problem is. -- gotom -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
