            Bug ID: 29907
           Summary: gdb tries to open /proc/pid/mem even for --version
           Product: gdb
           Version: unknown
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb

  Target Milestone: ---

Build systems (like QEMU's, apparently) may call 'gdb --version' to check g=
db's
presence & its version on the system.

As of 1bcb0708f22956d5128a2e75df6eba5a18327892, gdb will check if /proc/pid=
/mem
is writable, including for 'gdb --version' calls.

Gentoo's build process has sandboxing which blocks this access and then as a
result the build fails.

Is it possible to skip this the /proc/pid/mem check for simple --version
invocations? Thanks.
