the AT&T Software Technology ast alpha 2013-07-27 source release
has been posted to the download site
http://www.research.att.com/sw/download/alpha/
the package names and md5 checksums are
INIT 8cdf2460c146a7412ee1f2d37d19e3ce
ast-base 46a03d0e49840acedef8c0623cbef85c
ast-open f61766d8cb1f91c960a3a2a1385adcd6
ast-ksh 911d28c7263e90ec1e8037ad0b6db643
the md5 sums should match the ones listed on the download page
still verifying builds on some architectures
should be ok on linux & solaris
for the next week or so stability/regression patches will take priority
we have been seeing spurious "make: lost connection with coshell" in ast-open
builds
the current theory is that a signal is leaking through unchecked
it may be a flaw in the signal restart mechanism or a syscall that we missed
and requires an EINTR restart loop -- if anyone catches this one in the act
it would be a big help
