And another bug, signalled by a `frame missing closure' error, this
one even less frequent (maybe one in a million samples or so). I'll
see about hacking my profiler so that I can debug these problems.

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

You should run it past Michael Blair. If I understand correctly, he was
also doing statistical profiling and had run into either than exact same
problem or something much similar where it was difficult to impossible

Today I implemented a rudimentary statistical profiler for MIT Scheme.
In the process, I found a bug in the stack parser whereby it would
fail to parse stack frames that occur in the infrequent situation of
interrupting an internal compiled procedure that LIAR compiled with a
dynamic link; of cours
