i) Your subject line is wrong.  You do not "link" to BH, you use it to
include headers at compile time. That may seem like a small difference, but
it is not. You generally want to avoid linking as much as you can, if only
for cross-OS portability,

ii) This the R-devel list for R question. You have a package question. You
are generally advised to contact __the package authors__ and/or the package
mailing list. And yes, BH has one in


though I grant you that it is not as well advertised as it should be. I just
opened a ticket at https://github.com/eddelbuettel/bh/issues/3 to remind
myself to improve that.

iii) As for your problem, only you and some careful bisections can help you
there as we do not have your sources.  I too have packages including BH
headers, but they do not pull in abort() or other things the CRAN gatekeepers
prohibit us from deploying.
