Whoever has such exceptions and can compile their client from source, please do so. I have made changes to fix the wallet of such exceptions, it is the latest commit on github. I have never experienced such issues and cannot test if the additions will fix anything. I have tested them to prove they work but am not sure if the exceptions will no longer occur.
Fairly certain that the new commits will fix what is essentially a RAM issue.
~ I've seen the EXCEPTION: St9bad_alloc over flows on a system with comparatively low RAM, although a system with 16 GB of RAM appears mostly stable.
Has anyone else seen a Microsoft Visual C++ Runtime Library APPCRASH seemingly unrelated to the exception ? Which seems to happen more frequently when solo mining and/or PoS minting using an unlocked wallet ?
