Description of problem: qemu hit a build failure when compiling for mingw with -Warray-bounds enabled, and we traced the problem to a bug in assert.h not declaring _assert() with MINGW_ATTR_NORETURN, when contrasted with glibc's assert.h. Version-Release number of selected component (if applicable): mingw32-headers-4.0.2-1.fc21.noarch How reproducible: 100% Steps to Reproduce: 1. Compile something where a noreturn attribute changes what gcc is able to deduce with regards to warning generation. 2. 3. Actual results: See https://lists.gnu.org/archive/html/qemu-devel/2015-05/msg03020.html for a huge test case. I'm sure it's possible to come up with something much smaller and self-contained, but didn't bother spending the time actually trying to reduce it. Expected results: proper attribute in place, so that gcc has more knowledge for value range propagation Additional info:
This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '21'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 21 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
