--- Comment #2 from Nate Gallaher <nate+sourceware at jaybridge dot com> ---
I was able to reproduce this bug on Fedora 19, x86_64.
Reproduction required a slight modification of the recipe: the breakpoint in
malloc.c needs to happen at line 3865. This line will continue to change as
new versions of the library are released.
Required packages: glibc-debuginfo boost-devel boost-thread gcc-c++
[testuser@localhost ~]$ yum info glibc
Loaded plugins: auto-update-debuginfo, langpacks, refresh-packagekit
