SIGABRT on last day of simulation

[Aariq]

I've been doing some runs with IED_INIT_MODE=6 using custom .pss and .css files and almost every run I do errors on the last day of the simulation, seemingly regardless of when that day is, with something like the following:

 - Simulating:   06/29/2005 00:00:00 UTC
 === Time integration ends; Total elapsed time=    17273.0  ===
 ------ ED-2.2 execution ends ------
Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG IEEE_DIVIDE_BY_ZERO IEEE_OVERFLOW_FLAG IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
double free or corruption (!prev)

Program received signal SIGABRT: Process abort signal.

The end date of this simulation was 06/30/2005. I've also tried using 07/01/2005 as the end date, in which case I get this error after simulating 06/30/2005.

Should I be worried about this? It still generates all the .h5 files, but seems like it might not necessarily be safe to ignore.
