Extended Description
-glf as default turned out to show up several problems. Among them were several APEX benchmarks, including compiotaAKD.sac, which started running 10X slower and eating all the memory on my system. Here's a trimmed version excised from here, limited to just the APL reshape (genarray-ish) that shows the problem. With Build #16124 (containing many Bodo fixes already), the code leaves some sacprelude::sel() wrapper functions in the code. This not only slows things down, but inhibits WLF and EWLF.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
