Hi all
I've encountered an odd crash with OpenIFS cy40r1. If I compile with "fpe0" (Intel compilers, version 19.0.3) and run I get the following
489 forrtl: error (65): floating invalid

The crash used to be at line 198 in posddh, where it takes the NINDAT and finds the month of the run, i.e.
IDATEF(2) = (NINDAT - 10000*IDATEF(1) ) / 100
When I added a print statement at the line just above it, the crash did not happen there anymore, but a few lines down when OpenIFS uses NINDAT to find the day of the run.
My print statement shows that all values are totally fine. NINDAT, IDATEF(1) and IDATEF(2) are all what they should be, so I have no idea what the problem really is.
The backtrace is incomplete here. The problem seems to come from somewhere in libpthread and also master.exe, but I don't know where.
If I run without "fpe0" the model runs fine, but since I'm getting odd numerical instabilities somewhere I'd really like to be able to use "fpe0" to trap any crazy numbers.
I'm also using
export DR_HOOK_IGNORE_SIGNALS='-1'
Has anyone experienced similar problems before and know what the problem could be?
PS. Here are all the compiler settings:
