[MIT-Scheme-devel] compiler bug

2009-09-18 Thread Chris Hanson
FYI, while testing my most recent changes, I ran across a recent compiler bug. To reproduce: using the current compiler, do a fresh compile from sources. Then use that compiler to do another fresh compile. The second compilation hangs during the compilation of cref/anfile (the very first file
