NaN found at output of tmpbeis361.f (SMOKE-BEIS Version 4.8)

Good Afternoon

May you give me a hand regarding a NaN situation.

We ran smoke-beis version 4.8 and found NaN from line 1190 EMSIL in tmpbeis361. Also, there wasn’t NaN in output of normbeis361. Any suggestions where the NaN may generated?

TIA, Xiao
