https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98701 --- Comment #16 from Bahram.shahrooz at uc dot edu --- I spent a good chunk of today to debug.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98701 --- Comment #11 from Bahram.shahrooz at uc dot edu --- Thanks! This is how I compiled: gfortran FiberAnalysis.f -finit-real=nan -fcheck=all -ffpe-trap=zero,invalid -o FiberAnalysis_v2 This what I get after running (the answers are correct): Program received signal SIGFPE: Floating-point exception - erroneous arithmetic operation. Backtrace for this error: #0 0x105c4ad3d #1 0x105c4a16d #2 0x7fff203c4d7c #3 0x105c34e45 #4 0x105c3c653 #5 0x105c3cae6 zsh: floating point exception /Users/bahram/FiberAnalysis_v2 Saving session... ...copying shared history... ...saving history...truncating history files... ...completed.

Sorry, I don't know how to use -freal-init=nan. I tried to use it like this but got an error. % gfortran FiberAnalysis.f -freal-init=nan -o FiberAnalysis gfortran: error: unrecognized command-line option '-freal-init=nan'
