Error with .ge. 25 tags

[jinhyokh]

I am reporting an old bug. I had no problem running PSAT with 20 tags or less, but was not able to run with 25 or more tags. I could not track down what is causing the problem.

[bnmurphy]

How did the bug manifest? With the compiler or at runtime? Segfault? This sounds like a job for my new debugging skills :-)

[jinhyokh]

It was not a compiling or segfault issue. I dug up old logs from four runs with different tags. They seem to have had the same error. The following is a tail of one .out log.
