Hi. I went to the trouble of installing arch-linux in a vmplayer vm, and trying to repro this. I can't. If you're running gdb under gdb, and the child gdb is hanging, can you type Ctrl-C when it hangs, and then obtain a backtrace of the child gdb? It's been suggested to give the following a try. Does that fix things for you? bash$ export GC_MARKERS=1 before starting gdb It's a workaround for a libgc 7.4.0 bug. I verified my arch-linux has libgc 7.4.0, but I may have just gotten lucky.
