You have a memorylimit in your CLI(commandline) version of php. If you increase the memorylimit, or set it to -1 it should work. eztc sometimes needs lots of memory..
I upped memory to 128M. unfortunately it seems that eztc.php keeps compiling the same templates over subsequent iterations. i.e: keeps recompiling the standard templates even if I call it for corporate siteaccess. Now it runs out at half-way admin instead of standard, but ... issue not solved anyway. from docs, it would seem it should not recompile exixting templates. yet ...... it does.
