--- Comment #15 from Jonny Grant <jg at jguk dot org> --- Hi Richard I cannot reproduce DWARF errors without undefined references (by removing the implementation of a function). It is taking me a long time to reduce and still keep the error Which has different numbers /usr/bin/x86_64-linux-gnu-ld: Dwarf Error: Could not find abbrev number 2082833. Is a test case useful for this spurious error?
