Do I read it correctly that it creates PROT_NONE mapping on file opened
O_RDWR, then tries to create a PROT_READ|PROT_WRITE mapping from the
same file at fixed location and fails?
Why should it fail - because the fixed location is not suitable?
This is known longstanding issue: https://sourceware.org/bugzilla/show_bug.cgi?id=19838
But why has it come back? What kernel and glibc versions are you
using? This patch was supposed
to have fixed issue:
http://marc.info/?l=git-commits-head&m=138617700412279&w=2
I think the local-shmlba.diff patch was removed but I can't check at the
moment.
