Problem summary
USER AFFECTED: Users compiling a program with -g and using the addr2line tool on the resulting object/executable. PROBLEM DESCRIPTION: The addr2line tool issues an error message related to bad file number: 'BFD: Dwarf Error: mangled line number section (bad file number).' This was because the compiler was generating an incorrect line number mapping for DWARF debug information.
Problem conclusion
Fixed the line number mapping when we generate the DWARF debugging information.
