+Subject: [PATCH] src/actions.c: Include <config.h> in this generated file.
+
+On RHEL 5, because _GNU_SOURCE was not defined, open_memstream was not
+being declared, resulting in miscompilation and a segfault in the
+trace code whenever open_memstream returned a pointer >= 0x80000000
+(which would be truncated to a 32 bit int and then sign-extended).

  - virt-sysprep '--script' option (because it requires FUSE).
 
- - Enabling trace in multi-threaded programs may cause a segfault.
-   Appears to be caused by a bug in RHEL 5 glibc open_memstream(3).
