Description Daniel Drake 2011-10-27 09:54:36 EDT
Backtraces in threads on hardfp EABI systems segfault because they run off the end of the stack. This happens
because _start is marked with a .cantunwind but __clone is not. This crash gets hit frequently with java-based apps.

Test case: http://sourceware.org/ml/libc-ports/2011-08/txt00000.txt

Please could this already-upstream solution be added to glibc on F15+:
http://repo.or.cz/w/glibc-ports.git/commitdiff/3c6ac5cbe1b17f08bf66be4b1b1c6ffd01729af9

If it is acceptable as a %patch in the spec file, I'm happy to commit and build this myself.

Comment 5 Fedora End Of Life 2012-08-07 16:20:37 EDT
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached 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 to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

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.

The process we are following is described here:
