Summary: ICE on long class names
Product: gcc

module Molecular_Abundances_Structure
public
type molecularAbundancesStructure
double precision, allocatable, dimension(:) :: molecularValue
end type molecularAbundancesStructure
contains
double precision function Molecules_Abundances(molecules)
implicit none
class(molecularAbundancesStructure), intent(in) :: molecules
return
end function Molecules_Abundances
end module Molecular_Abundances_Structure
Looking at gfc_new_symbol:
Breakpoint 1, gfc_new_symbol (
name=0x7fffffffd5f0
"__class_molecular_abundances_structure_molecularabundancesstructure",
ns=0x148b420) at ../../trunk/gcc/fortran/symbol.c:2551
2551 gfc_internal_error ("new_symbol(): Symbol name too long");
(gdb) p name
$1 = 0x7fffffffd5f0
"__class_molecular_abundances_structure_molecularabundancesstructure"
... which, because we put _class_ before the name, is longer than the
maximum symbol size GFC_MAX_SYMBOL_LEN.
