test: bug repro for vm function redefinition

cjihrig · cjihrig · commit 48e70092aa94 · 2016-03-03T11:56:22.000-05:00
This commit adds a failing test case for the vm module. Currently, if runInContext() defines a function, and a later call to runInContext() redefines the same function, the original function is not overwritten. Refs: #548
