Re: Need help finding heap corruption bug

[Pat Lasswell]

The goops failures are a side effect of a change I made to (initialize <generic> ...) so that adding a method to no-applicable-method wouldn't crash; the warning arises from the generic function having one method instead of none after define-generic is called.  There are details on bug-guile here:

http://lists.gnu.org/archive/html/bug-guile/2006-09/msg00002.html

It seems that char 254 doesn't behave as expected in regular expressions on this platform.  

I backed out the change to initialize <generic> and make check lists only the two failures for regexps with char 254, but the same steps still corrupt the heap.

thanks

Before investigating any further, does Guile 1.6.8 "works" on Intel
Macs?  Is it under MacOS X?  For instance, did you successfully run the
test suite (type `make check' under the top-level source directory)?

Thanks,
