I also cannot reproduce it. In my test build HAVE_BACKTRACE is set to
1 in config.h, and in the configure output I see:

checking for library containing backtrace... none required
checking for backtrace... yes


Thomas, can you save the strongswan build output somewhere, or check
the output of the above checks and the value of HAVE_BACKTRACE ?

Thanks,
Thomas
