--- Comment #4 from David Malcolm <dmalcolm at gcc dot gnu.org> --- I'm not sure how best to debug this. $ echo _Z15fname_as_stringi | c++filt fname_as_string(int) and indeed, that seems to be just for the C/C++ frontends, not for libgccjit. Some ideas: Given: bootstrap-emacs:/usr/local/lib/libgccjit.so.0.0.1: undefined symbol '_Z15fname_as_stringi' ld.so: bootstrap-emacs: lazy binding failed! ...it appears to be an issue with dynamic linkage. You could try turning up the verbosity of the dynamic linker; if it's glibc you could try setting LD_DEBUG=all in the environment, which I believe is the most verbose option (see "man ld.so" for other options, if that's overkill). Hopefully that will give a hint as to where that symbol is coming from. If that doesn't help, is there a way to figure out what the command line is at the point of failure, and what it's trying to do?
