[SAC-HELP] glibc detected (when trying to get polezeros using rdseed)

[Arthur Snoke]

Carl,  a couple of comments/questions.

First, after sending my message last night I realized it was incomplete: 
In my experience, on all platforms one often finds that a build on a 
release may not work on earlier releases if dynamical libraries are 
involved.  What may be different about Linux is that it may work only on 
the same release it was built on.  The earlier reported problem on SAC on 
Linux 64 may have been because the build was on a later version.

Next, did you do your test with the built-from-sources RDSEED v5.1 build?

I got similar warnings to the ones you got when I built v5.2 beta on my 
Mac OS 10.6.  Interestingly, no warnings when I built it on OS 10.4 Intel. 
Those warnings do not seem to matter.

RDSEED v5.1 has several new features -- especially dealing with polezero 
files.  As is often the case, new features may lead to new bugs.  Working 
with them on getting compatibility between RDSEED and SAC led to a few of 
the changes between the pre-release and final versions of SAC v101.5. 
Aside from the polezero stuff, the main changes I can recall off hand fro 
a SAC point of view is that now the default EVDP is kilometers and 
CONSTANT is no longer defined.

I suggest you make your SEED volume available to Rob/IRIS as Rob wants to 
check to see if this might be a new bug.  As they can be large, I suggest 
you put it on a Web site and tell Rob/Chris where it is.  Otherwise, Rob 
can probably write you (off list) instructions about how you can 
upload it to an IRIS server.  (Chris is the one who had been working on 
RDSEED, but I think he is on vacation right now, so write both.)

p.s.  What is the day for you with the earliest sunset?  For us it is 
around December 6.  We have already gained four minutes.  The latest 
sunrise will be around January 6.  However, by local time it was the last 
day of Daylight Savings time.
