It has to be a directly executable binary. A cmd file is not directly executable, as it has to be launched with %comspec% and that knowledge requires a higher level API like ShellExecute instead of the low level CreateProcess that is used here. As already mentioned downthread, if you want a core dump you should simply set error_start=c:/cygwin/bin/dumper.exe, modulo dumper bugs (which should have all been fixed in the latest version.) If you really must run a cmd file, then you need to create an .exe wrapper program that execs %comspec% /c "dump.cmd (original args)" or similar.
