[racket-dev] continuation-mark-set->context Regression on 64 bit Linux

On 64 bit Linux, `continuation-mark-set->context' doesn't provide any
stack trace anymore, instead always returning the empty list. It was
working at least up to 5.3.4.

When the JIT is disabled, I get the expected stack traces.

This regression breaks the profiler, the contract profiler, and the profiling
features of the Optimization Coach.
