I'm using VS 2015 RTM to debug Chromium build with VS 2015 RTM. Normally this works but in at least one case the local variables suddenly disappear when entering a particular scope. This changes debugging from being pleasant, easy, and approachable to being ninja-hard-assembly-language-and-registers annoying.

In the attached screenshots you can see that when the cursor is on "if (error || cache_entry->dirty()) {" the local variables are shown. When I single-step over this line of code they all disappear. Aaaggghhhh!!!!!

Yes, this is a bug with Fastlink. It will be fixed in the next release of Visual Studio 2015.

I removed win_fastlink=1 from GYP_DEFINES, which disables the /DEBUG:FASTLINK feature, and this avoided the problem.

So, it appears that /DEBUG:FASTLINK may be broken.
