GDB remote debugging with valgrind

Question

If I remote debug using gdb I connect to the gdbserver using

target remote host:2345

If I debug memory errors with va

Answer 1

Can I combine the two to debug memory errors on a remote machine?

Yes: current vgdb accepts --port= argument since this commit:

r12204 | sewardj | 2011-10-22 13:38:08 -0700 (Sat, 22 Oct 2011) | 5 lines

So run vgdb --port=2345, and then (gdb) target remote host:2345 as usual.
