Internal error in syntaxcheck test

[Jeffrey Hugo]

I'm encountering an odd error in the syntaxcheck test, and I'm trying to 
debug why.  Any pointers would be appreciated.

An example instance of the error I get:

FAILED [HIGH] AMLAsmASL_MSG_CONSTANT_EVALUATION: Test 1, Assembler error 
in line
6136
Line | AML source
--------------------------------------------------------------------------------
06133|                     If (LNotEqual (ToInteger (Local0), 0x00))
06134|                     {
06135|                         ShiftLeft (Local0, 0x04, Local0)
06136|                         Store (Concatenate (Concatenate 
(Concatenate ("USB[", "0"), "]: Fused Value for TUNE2: "), ToHexString 
(Local0)
      | 
          ^
      | Error 6014: Could not evaluate constant expression    (AE_NO_MEMORY)
06137|                             ), Debug)
06138|                     }
06139|                     Else
================================================================================

ADVICE: (for Error #6014, ASL_MSG_CONSTANT_EVALUATION): Failed to evaluate a
constant expression, the compiler could not resolve a subtree for some 
unknown
reason.

I may be wrong, but this reads like some kind of internal error in the 
test, rather than an issue with the DSDT table.

The only odd thing is that for some reason, the disassembly split the 
source line into two - 06137, above, is really a continuation of 06136.

Manually disassemblying my compiled source with iasl -d, I see the same 
odd split, but recompiling the disasembled source with iasl does not 
generate any errors.

I first see these errors with tag V16.05.00.  I did a git bisect between 
V16.03.00 and V16.05.00, which pointed me at:

     Changes in this release of ACPICA are detailed at the following
     link on the ACPICA developer mailing list:

Is there some weird interaction between how FWTS runs syntaxcheck and 
current versions of ACPICA?
