I have encountered a segfault on the matchengine, until I only opened limit orders it worked fine, but after I opened the first stop limit it started to collapse.

Which version are u using?

[dogewithit]

cemkod:master at latest commit (7e3b06b), I also used to cherry-pick from viabtc:master, but the first time i got this issue was before injecting code from that branch (viabtc:master).

Until we solve this issue I moved the engine to viabtc:master using the same database structure (it works fine).

Please, use #7 this pull request.

I also tried to cherry pick and rebuild the commits on #7 but it didn't fixed the problem
