segmentation fault
« on: December 08, 2014, 03:31:53 AM »

0.4.24 -- it seems like everytime I finally get the blockchain downloaded and make a transaction, the program crashes and I get a segmentation fault.

then it won't restart, unless I resync the blockchain. I just spent several hours syncing the blockchain only to immediately hit this for the second time today.

anybody know how I can work around this bug?

KEY9EZUvQjARsbqxC☻DQ261f6irmi1MxJj89 was entered an address somehow it got validated on the chain... maybe random maybe a hacker.

Opened a thread about it here...https://bitsharestalk.org/index.php?topic=12075.new#new


my symptoms were seeing scan failures running as a delegate.

I had same issue and I solved that deleting the mail folder!!!  ( inside  .Bitshares folder ) before rerunning the wallet (or resseting the wallet database )

That worked like a charm for fixing the segmentation fault.

Now I just wonder about this failure during transaction thing everybody else seems to be getting too...

Although deleting the mail folder seems to work it doesn't fix the underlying bug.

I believe this is the same bug as this one, in which a closure in part of the BitShares mail code captured a variable by-reference that went out-of-scope. That particular bug was fixed 26 days ago in the master branch, but since nearly everyone is on v0.4.24 and v0.4.25 has yet to be released, people would still be exposed to that bug.

So, if you are compiling from source, you could check out the master branch from git and compile that, and I think your problems should go away then (or don't and just wait for v0.4.25 if you want to be extra conservative and safe). If you depend on the pre-compiled executables, then you have no other choice then just waiting until v0.4.25 is released and just keep deleting the mail folder every time you make a transaction that causes a segfault.

ahh thanks for spelling that out. I am compiling, and I think i'd prefer a conservative approach, so I'll just keep deleting the mail folder. :)
