Hello, while trying to port some code from CHICKEN 4 to CHICKEN 5 I have just spent several hours tracking down a crash to a call of hash-table-ref/default for a table which happened to use eq? as the comparison function and was loaded with various types of objects as keys.
Then I realized that eq?-hash simply cannot be called on certain types of objects: $ chicken-status [...] srfi-69 ....................................................... version: 0.2 [...] $ csi CHICKEN (c) 2008-2018, The CHICKEN Team (c) 2000-2007, Felix L. Winkelmann Version 5.0.0rc1 (prerelease) (rev 9d480412) linux-unix-gnu-x86-64 [ 64bit dload ptables ] #;1> (import srfi-69) ; loading /opt/chicken/lib/chicken/9/srfi-69.import.so ... ; loading /opt/chicken/lib/chicken/9/srfi-69.so ... #;2> (eq?-hash 2/3) [panic] out of memory - heap has reached its maximum size - execution terminated Apart from fractions, complex numbers also seem to trigger the crash reliably. Since I don't see any obvious reason why hashing by object identity should be impossible for certain values, I consider this a serious bug :-/ Ciao, Thomas -- The greatest victory is that which requires no battle. -- Sun Tzu, "The Art of War"
