infinitely long scan #155

Open almaz045 opened 3 months ago

almaz045 commented 3 months ago

I tried run "atom reachables -o app.atom -s reachables.json -l c ." on tarantool repo to test C lang. Then it's printed: "Exception in thread "" java.lang.OutOfMemoryError: Java heap space" Then I tried to run atom with next command: /atom/bin/atom -J-Xmx16g reachables -o app.atom -s reachables.json -l c .

But it scans infinitely, I waited for couple hours.

Then tried like this: atom/bin/atom -J-Xmx16g reachables -o app.atom -s reachable.json -l c . -J-XX:+UseG1GC -J-XX:+UseStringDeduplication

And it scans infinitely too

Completes within a minute for me with the default. Do you have the latest atom?
