It's due to how the mmap logic was developed in glibc. Current logic will round the map-address up to the next SHMLBA alignment which may be wrong on parisc since the platform has specific hardware cache constraints which renders shared mappings then possibly not being in sync between different CPUs. > Anyway, in that case > instead of modifying a generic file common to all architecture, you > should create a <ports/sysdeps/hppa/libc-mmap.h> with the HPPA specific > value. True. > Now that patch local-shmlba.diff from bug #725508 has been applied, is > this patch still needed? That's correct. This patch here is not needed any longer then. You can just close this bug report (or mark it as duplicate of #725508). Thanks! Helge -- To UNSUBSCRIBE, email to debian-glibc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
