gcc fpe errors in time_interp_external2

[rem1776]

Describe the bug
Occasionally on the amd box and in the ci, this line generates a floating point exception:

FMS/time_interp/time_interp_external2.F90

Line 857 in d13c129

hi_tmp_src_data = real(field%src_data, r4_kind)

I've seen the same error happen with two of the tests, test_coupler.sh test 3 and test_data_override2_mono.sh test 1.

To Reproduce
compile with gcc 13 and debug flags (-O0 -fbacktrace -fbounds-check -fbacktrace -ffpe-trap=invalid,zero,overflow), then run either the coupler or data_override tests a couple of times until it comes up.

Expected behavior
Not fail, all tests should be pass with debug flags.

System Environment
amd box with gcc 13.3.0 + mpich.

Additional context
This is preventing #1579 from working. On the amd box these error don't happen every run, but in the ci it seems to fail every time (maybe due to it running 7 different instances, one failure is bound to happen).

field%src_data is a pointer, and hi_tmp_src_data is an allocatable, so that likely has something to do with it.
