I do, but I've since determined that I was somewhat confused, and the
issue does not appear to be platform specific. To sum, read/fread
will not raise a SIGSEGV when writing to memory protected PROT_READ,
but simply return an error. Why I've only run into this issue when
building gcl/acl2 on m68k I do not know. Furthermore, I cannot
reproduce the failure in
http://buildd.debian.org/fetch.php?&pkg=acl2&ver=2.7-8&arch=m68k&stamp=1076124966&file=log&as=raw
on crest, so at present I can only surmise that the old read/fread
issue is randomly at work from the similarity with the failure a year
ago. I've just uploaded gcl-2.6.1-24 which protects all read/freads
against this problem. Soon I'll release another acl2 build-depending
on this version, together with more diagnostics in the build record
around this failure. As all appears to work flawlessly on crest, I'm
hopeful for success.
Take care,
