It might be useful to compare the two decls that invoke the mismatch that
triggers the gcc_assert:
prevailing-decl is:
function_decl 0x7fb0f574f900 convect_satmixratio
type function_type 0x7fb0f5786b28
type void_type 0x7fb0f584cd20 VOID
align 8 symtab 0 alias set -1 canonical type 0x7fb0f584cd20
pointer_to_this pointer_type 0x7fb0f584cdc8
QI
size integer_cst 0x7fb0f583d758 constant 8
unit size integer_cst 0x7fb0f583d780 constant 1
align 8 symtab 0 alias set -1 canonical type 0x7fb0f5786b28
public external QI file bkfconv.f90 line 517 col 0 align 8
whereas e-decl is:
function_decl 0x7fb0f574f600 convect_satmixratio
type function_type 0x7fb0f5763b28
