update: I set up some vps instances and found this to be repeatable on 32 bit machines only with both TITAN and non-TITAN accounts. Every 32 bit machine crashed, and no 64 bit machine crashed.

When trying to compile with clang, I get an undeclared reference to '__atomic_load_8'
which is apparently a bug in which is fixed in gcc 5:
https://llvm.org/bugs/show_bug.cgi?id=23262
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65147

When trying to run bitshares_client compiled with gcc 5, I found bug #1527, so I haven't been able to verify if this fixes anything yet.

I have the correct thread backtrace, vikram I sent it to you via pm on bitsharetalk in case private keys can be deduced from any of the data

I just upgraded a machine from 32-bit to 64-bit OS by doing a package-by-package crossgrade. bitshares uses 1/2 the memory and is significantly faster on the 64 bit OS on the same hardware, perhaps there is memory leak in 32 bit? When doing wallet maintenance memory slowly creeps up to ~4 GB then the segfaults happen on bit bit, but stays < 2 GB on 64 bit.

Perhaps because that the memory leak issue is "fixed" in v0.9.1?

0.9.1 still crashed and used lots of memory on 32 bit but not on 64 bit. I tested on real hardware and vps, repeatable across all.
