Nallatech 385A Quartus Fitter Failed

I could use some help compiling a fairly simple, Intel authored OpenCL kernel on a Nallatech 385A (GX1150). After about four hours after running the following command (or with the default board p385a_sch_ax115 and various other attempts)

aoc -v -report sha1.cl -DALTERA_CL -DFPGA -board=p385a_min_ax115

we get the following output:

aoc: Environment checks are completed successfully.
aoc: If necessary for the compile, your BAK files will be cached here: /var/tmp/aocl/gm78
You are now compiling the full flow!!
aoc: Selected target board p385a_min_ax115

Not sure which log(s) are relevant to tracking down the problem. Please let me know and I can post the additional information.

Many thanks.
