Debugging workflow

[jeroen]

I would be very interested in a brief tutorial or demo by @jimhester or @kevinushey in debugging a C problem without printf(). Preferably on both MacOS and Windows. cc @jennybc.

Windows is a bit of a pain, but I have managed to do it before so could probably get it working again to demo

[kevinushey]

I'd like to see @jimhester's debugging workflow too :-)

I could try to prepare something worth showing. One of the nice things about R on Windows being built with MinGW is that the bundled gdb.exe seems to work well when attached to R.

[jeroen]

You better share some of that sweet synergy @jimhester :)

Not to spoil anything too much ;), but does the workflow have a call to R -d gdb somewhere along the way?

I would like to see @jimhester's debugging magic as well
