--- Comment #26 from Mark Millard <markmigm at gmail dot com> --- (In reply to Mark Millard from comment #19) (In reply to Mark Millard from comment #25) I think I've identified 2 problems: comment #19 reports, in part: QUOTE Looks like linemap_lookup (in line 843) is returning the null pointer value and the calling/using code does not check for or handle that. I've currently no clue why the null pointer is returned. END QUOTE comment #25 reports, in part: QUOTE I'm not sure why .build/./prev-gcc/xg++ is in use for this check, leading to the need for libstdc++.so.6 being available. END QUOTE I'll add here to that last: when it need not be available at that point. Having a lang/gcc* already installed can lead to one being available via the ELF config search path. (Not true of the poudriere jail for a normal poudriere bulk build.)
