Soar hard crashes on epmem retrieval

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Load the following agent:

# Soar crashes at d 1 e 2

epmem --set learning on
epmem --set trigger dc

sp {init
    (state <s> ^superstate nil)
-->
    (<s> ^name buggy
         ^1 <whatever>) # this fails
         # ^one.1 <whatever>) # this doesn't fail
}

sp {propose*test
    (state <s> ^name buggy)
-->
    (<s> ^operator.name test)
}

sp {apply*test
    (state <s> ^operator.name test
               ^epmem.command <ecmd>)
-->
    (<ecmd> ^query.name buggy)
}

2. Run it

What is the expected output? What do you see instead?

Expected output: Soar doesn't crash.
Actual output: Soar crashes.

The XNLSoar system also crashes in the same function, although under different 
circumstances. To reproduce, download the attached files and put them in the 
same directory. cd into that directory in the debugger and load test.soar. Run 
2 decision cycles.
