Re: [patch+7.5.1] Work around PR libc/13097 "linux-vdso.so.1" #3 https://sourceware.org/ml/gdb-patches/2012-11/msg00636.html Message-ID: <20121125181505.GA26194@host2.jankratochvil.net> It is pending/unreviewed/unapproved. Also I am not sure it is really still an issue on latest upstream glibc, it is not an issue on Fedora 21 x86_64 glibc with the reproducer from: https://sourceware.org/bugzilla/show_bug.cgi?id=13097 (That is old Fedoras workarounded it in glibc, then some Fedoras exposed the issue in GDB but now it is not visible - so either Fedoras workaround it again or just upstream glibc switched/workarounds it also.)
