[elephant-devel] elephant 1.0 is unstable under Clozure Common Lisp Version 1.5-r13651 (LinuxX8632)

[Xu Jingtao]

hi eslick:
This problem will also occure in 1.4,but not so often.

If i try my operation one or two times,the operation will work fine again.

eslick> Did you have this problem in 1.4?  We use Elephant extensively on Clozure on Mac/Linux under 1.4 but I haven't upgraded to the latest 1.5 on any system that I'm aware of.  There are some occasional bugs found in the schema management code too that may be lurking.
