I got a segmentation fault followed by the error in the title (\*\*\*longjmp causes uninitialized stack frame\*\*\*: CMAQ.exe terminated) in the CMAQv5.3.1 standard output file, as shown below: ![image](https://canada1.discourse-cdn.com/flex027/uploads/cmas/original/1X/3dc0a8d53b330d03b9a70a5f5f692d9efb73b092.png) ![image](https://canada1.discourse-cdn.com/flex027/uploads/cmas/original/1X/b2be367852dbb64c2a6e8648e7ded4ae77d7a912.png) However, there is nothing in the standard error file or the CTM\_LOG\_\* files where all input files are successfully read. I am using the bug-fix version of CCTM/src/cio/centralized\_io\_module.F at [https://github.com/USEPA/CMAQ/blob/master/DOCS/Known\_Issues/README.md#cmaqv531-i5](https://github.com/USEPA/CMAQ/blob/master/DOCS/Known_Issues/README.md#cmaqv531-i5) to compile CCTM. Runscript, standard output/error and one LOG file are attached.[run\_cctm\_2016\_12US1\_stamp2\_12US2\_testrun\_myfix\_22may2020.csh](https://forum.cmascenter.org/uploads/short-url/sqTQHNCybS47vNsVySLvWTuHg4i.csh) (46.2 KB) [slurm-5733324\_4294967294.out.txt](https://forum.cmascenter.org/uploads/short-url/Uldur0Nsc6mzzHjqjAZSBVIn85.txt) (25.0 KB) [slurm-5733324\_4294967294.err.txt](https://forum.cmascenter.org/uploads/short-url/siSEWLLGUlmj6Duws6AnWXq9cbd.txt) (43.1 KB) [CTM\_LOG\_047.v531\_intel\_2016\_CONUS\_20140102.txt](https://forum.cmascenter.org/uploads/short-url/wV8GRUEyvdx4qrgZ7zmKOFc2ZH2.txt) (36.7 KB)
