Didn't crash in my system. Does it also crash when using the gradient tool?

Yes. Just retried with the same file. Same effect with the gradient tool.
Interestingly. It only seems to happen when i drag it across the mid section of the arm. If i drag towards the hand nothing happens. If i drag towards the hand without letting go, and drag towards the mid section again, i also crash.

When the project is loaded try not to move the view at all. And just do the gradient from the getgo.
That produces a crash on my side

Try running blender_debug_log file. And attach the generated log file.

Thx for the report!
Can reproduce in 2.81a.
However this seems fixed in current master.

Will assume this is fixed already (@jack conradsen (STANN.co) please check a fresh build from https://builder.blender.org/download/, if this is still crashing for you in a fresh build, please report back, we can always reopen this report then...)
