I'm getting the following on a couple of files when I build.
16> Internal error: assertion failed at: "shared/cfe/edgcpfe/cmd_line.c", line 11641
can you send the .i file?
I think this is the same as DPD200292117 which has been fixed just in the last week or so.
The problem occurs when old style for loops are enabled with the /Zc:forScope- option and you are using MSVC++ 2012 (where c++11 range based for loops are enabled). These two kinds of loops are not allowed to be used together, but we should allow the option and only give a warning when we see an actual range based for loop in the code.
This should be fixed in the next update. Sorry for the inconvenience.
