crash in CMerkleTx::GetDepthInMainChainINTERNAL() #3997
Description
I've been running bitcoin-qt inside gdb for over a year now, because it used to crash pretty often. It just crashed for the first time in over 6 months, a week or two after upgrading to the recent release. I would guess this is a new issue introduced in 0.9.
I built the code myself, from the git v0.9.0 tag, on a 64 bit Linux system.
Here's what gdb said:
Program received signal SIGSEGV, Segmentation fault.
