i encountered the same problem. I took a look at L2A_Tables.py and as far as i understand, the function gdalDEM() is trying to call gdal from shell (Lines 1000-1004):
callstr = command + arguments + srtmf_src + self._DEV0
if(subprocess.call(callstr, shell=True) != 0):
self.config.tracer.fatal(shell execution error using gdalwarp')
sen2cor is downloading dem data from the server to SEN2COR_HOME\dem and unzipping is working too.
It seems there are some problems for sen2cor to access my gdal library giving the fatal error "shell execution error using gdalwarp"
sen2cor is running without Terrain Correction on 20 and 60 m resolution.

Any ideas on how to solve the problem?
Thanks in advance
