Please include the complete backtrace with any bug report. See <https://gcc.gnu.org/bugs/> for instructions. The relevant source code is in https://pla.esac.esa.int/pla/aio/product-action?COSMOLOGY.FILE_ID=COM_Likelihood_Code-v3.0_R3.01.tar.gz This broke in trunk relatively recently, though at least a month ago. I don't have a reduced test case (this is not my code).
