Unwinding stack on PPC 64 corrupts CR
Last modified: 2007-12-11 16:10:38 EST
During gcc testing we discovered a bug in the kernel unwinder data which causes
the CR register to be corrupted when throwing an exception through the vDSO.
There is a patch applied upstream.
There is a test case at http://gcc.gnu.org/ml/gcc/2007-10/msg00184.html
This bug is preventing some packages from ebing built.
*** Bug 298071 has been marked as a duplicate of this bug. ***
This patch looks reasonable to me.
Created attachment 237451 [details]
Patch to fix the kernel
Fedora 8 blocker??
It is for me, I can not rebuild eclipse-subclipse por ppc64 users, leaving a
broken upgrade path for them, see Bug #298071
Okay, in Fedora 8 kernel CVS.
Fix is in Fedora 8 release.
Fixed for FC6 in kernel-220.127.116.11-70.fc6
