As it was pointed out in the issue 37365, the reason for this behavior is the inability of Sage to recognize QEPCAD's error in the non-interactive mode.
The error can be seen in running QEPCAD in the interactive mode with interact=True, or in verbose mode with verbose=True, although the latter is currently broken. Alternative is to use parameter logfile='myfile.log' and inspect the file myfile.log afterwards. Under Linux it's also possible to specify logfile='/dev/stdout' as an alternative to verbose=True.
The error in this case is "Too few cells reclaimed". The number of cells is controlled by memcells= parameter to qepcad(), although increasing it in this case up to 10^8 does not seem to help.
