[FLASH-USERS] [EXT] Re: Segmentation fault after file modification

[Hansen, Eddie]

The line calculating ‘radius’ needs to go inside the I,j,k do loops. Also, keep in mind that his is radius^2 (maybe that’s what you want for your modifications).

I can share that, and the debug message I get after I have added the "-debug" flag as well. Here is the debug message,

At line 119 of file IO_writeIntegralQuantities.F90
Fortran runtime error: Index '1997467855' of dimension 1 of array 'xcenter' above upper bound of 24

Error termination. Backtrace:

And attached is the modified file.

Hello,

It depends on how you modified it. If you share your modified routine, someone might be able to find the bug.

Hello,

I recently modified IO_writeIntegralQuantities.F90, and in doing so, I've gotten a segmentation fault issue. I am trying to track it down, but am having some trouble, are there some ways I can go about doing this? Any suggestions? Help is appreciated!
