There is evidently also a bug that makes uenvir.scm fail to find a
static link for certain stack environments. This occurs extremely
infrequently, though: about one in ten thousand or one in a hundred
thousand samples, in my profiling of the compiler compiling the
runtime. I can still get useful information by just discarding the
samples on which the stack parser crashes, but I'd like to fix this
problem at some point.
