segfault using console-solver when checked out from source #16

Closed ghost closed 3 years ago

ghost commented 3 years ago

If I build from source on linux I keep getting a segfault when testing the console-solver, here is the backtrace, it seems to work fine when single threaded, but 2 threads or more and it crashes, also the precompiled download works fine with 8 threads.

run with 2 threads
