            Bug ID: 15959
           Summary: GDBserver hangs when started with --wrapper
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: server
          Assignee: unassigned at sourceware dot org
          Reporter: qiyao at gcc dot gnu.org

Use option --wrapper for first time, and get GDBserver hang there,

$ ./gdbserver/gdbserver --wrapper env TEST=5 -- :1234 ../foo.exe
Process ../foo.exe created; pid = 15074

GDB shows it hangs in sigsuspend
