#119 magic exits during LEF generation with kill signal Issue opened by SweeperAA After GDS write completed and during LEF generation, magic exits with a

kill signal

. This occurred in the openlane docker with magic version 8.3.87 on the openlane develop branch (checked out Nov 30). I've provided context of the log below and a link to the routed DEF and

merged.lef

files (the routed DEF was over 400MB so I had to break up into 10MB compressed archive chunks using 7zip).
