We are migrating from gperftools/tcmalloc 2.0 to 2.8. But some of our test cases fail with "out of memory" error. We use Cent OS 6.5. This happens with a posix_memalign() call requesting for 32536008 bytes with 64bit alignment. I didn't use any specific options with configure while installing gperftools. Has anyone faced something similar with tcmalloc 2.8 ? Thanks, Pramod

This is caused by bug. Bug is fixed in recently released 2.8.1 version. Please upgrade.
