Well, I guess I had several issues at once, possibly also memory corruption due some instability (did try to enable internal DCDC like 14 days ago, it was unstable so I turned it back off, restarted, rebooted but maybe it still left the cpu still in some broken state as very same code that was randomly unstable in now stable). But after trying with different device it looks like maybe there is some memory leak? I create software spi via new SPI() then delete it and variables go down by one. Tried few times and always free variables go down by one after deleting it. Also E.dumpFragmentation() shows some suspicious 'L' near the end which seems to be increasing after each attempt, see full log here

variables go from 602 to 601 and 600. Or is there other explanation for free variables going down like this? like command history or something else
