It can be pretty helpful, at least to see at which point in Cygwin the error occurs. Did you call gdb in default GUI mode or in non-GUI? Mostly the non-GUI version (started by calling gdb -nw) is a bit easier to control, especially if you're working with more than one partition since the GUI version only works with native paths. > If I build cygwin from source would I be able to see where the write was > failing? Sure. You can build with CFLAGS=-g instead of using the default of CFLAGS=-O2. That results in a easier source code level debugging. When you're running that dll (which is approx. 4MB in size) you can start rsync again under gdb control. In gdb you can load the DLL's symbol table by calling `dll cygwin1.dll'. Set a breakpoint on rsync's main() function and after running up to that point you can set breakpoints to Cygwin's internal functions. Lapo, are you already investigating into that problem as well? Since you did the base port you have a clue what's going on, perhaps.
