A smaller test case
This requires use of the -std=c++0x option when compiling but cuts out some of the noise in the test case by replacing the trivial pthread wrapper classes in the previous attachement. Exhibits the same symptoms.
This is a test blocker for us because it causes significant instability in the messaging broker on RHEL6. Before anything else is tried, this patch should be added to the RHEL6 glibc and then all tests repeated: http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=5f24d53acb2cd02ffb4ac925c0244e4f1f854499;hp=d84acf388ed8b3f162dda0512139095bfc268beb *** Bug 586972 has been marked as a duplicate of this bug. *** Red Hat Enterprise Linux Beta 2 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. |
Created attachment 414918 [details] test case Description of problem: Seeing 'invalid fastbin entry (free)' errors for a test program that appears to have no bug in it that would legitimately cause such an error. Suspect this may be a bug in the fastbin verification logic. Version-Release number of selected component (if applicable): glibc-2.12-1.1.el6.x86_64 How reproducible: Easily Steps to Reproduce: 1. compile and run attached test case Actual results: Get a crash due to an invalid fastbin within a minute. Expected results: No crash. Additional info:
