I'm getting a bus error running a macro, when the

correlate master 1 number 350 length 20

instruction is executed to cross correlate two series of 896001 samples each.

Tested on Mac OS X 10.5.x and 10.6.x, with 32 and 64 bit Sac v.101.4.
Was giving the same error with v.101.3b. RAM on the test machines goes
from 3 to 12 GB.

If I use only one window, like in

correlate master 1

the bus error does not occur. Also, the bus error does not occur if I
decimate the samples before cross correlating.

NOTE: The same macro, with the same data, still works on an old Sun
workstation with SunOS 5.9 and Sac Version 00.58d, 3GB RAM, no need to
interpolate or use a single window

Is there a known limitation on the number of samples in current Sac,
with respect to the old version 00.58d, or could it be a bug hidden

Just in case, I have a tgz file (about 4MB) with macro and input data
ready for testing, if there is interest.
