Bug: bitcoin GPU recovery is broken since olcHashcat 1.37 till current (hashcat 3.10)

[md55]

I tried to recover test wallet.dat from this post http://www.gobitgo.com/articles/1005/How...-Password/

I created dic with 1 pass: GoBktGo
Latest hashcat-3.10 can find it on CPU:
Status.........: Cracked
but can't find on GPU:
Status.........: Exhausted

Hashcat introduced 11300 Bitcoin type since 1.36 so I tested some versions on GPU:
oclHashcat-1.36  found
oclHashcat-1.37  no
oclHashcat-2.01  no
    hashcat-3.00  no
    hashcat-3.10  no

oclHashcat-1.36 - is the only version worked right with test pass

My config:
Windows 7 x64, no SP
HIS Radeon HD 6990 (Device #1: Cayman, 512/2048 MB allocatable, 24MCU)
amd-catalyst-15.7.1-with-dotnet45-win7-64bit
