Yes, you can reuse backtrace_state objects. > 2. The reason I'm invoking dladdr instead of backtrace_syminfo is the need to > obtain the name of the module containing the symbol.

In libbacktrace/elf.c, elf_syminfo() does not seem to walk the chain of > elf_syminfo_data (i.e. does not use edata->next). Is that a bug? Hmmm, yes, that does look like a bug. Whoops. Ian
