We are trying to convert several data sets from Grib2 to Grib1. I know, we are still using grib1. :).
We are using these libraries on a Rocky 9 system. We have installed all the libraries required and build the grib-util. We are able to convert most of the data sets we use like GFS and NAM. However, with the RAP 20km we are seeing malloc errors when trying to convert it. It appears there are 7 files within this file that can cause this to happen. One of the files is the Haines Index, which I have attached the grib2 file for. When I run cnvgrib on it, this is what I get:
cnvgrib -g21 haines_index.grb2 haines_index.grb
malloc(): invalid next size (unsorted)
Program received signal SIGABRT: Process abort signal.

We use this in centos 7 without issue, so this could be related to moving to Rocky 9. Maybe something in the build process or something with libraries with respect to Rocky 9.
I looked through your previous issues and didn't see this mentioned.
Any thoughts on what could be happening? We will continue to try and debug things on our side. But I wanted to at least mention it.

I pulled the data from here: https://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/MT.rap_CY.11/RD.20240808/PT.grid_DF.gr2/
The raw files are named like this: fh.0004_tl.press_gr.us20km
