This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. Memory allocation comes from posix_memalign(). ElectricFence just doesn't know about that one: # objdump -T /usr/lib64/libefence.so | grep memalign 00000000000019e0 g DF .text 0000000000000422 Base memalign Created attachment 426561 [details]

Fix
This patch adds the support for posix_memalign to ElectricFence.
Red Hat Enterprise Linux 6.0 is now available and should resolve the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you. |
