--- Comment #8 from David Keller <david.keller at litchis dot fr> 2012-08-15 15:55:16 UTC --- According to http://www.freebsd.org/cgi/query-pr.cgi?pr=28191, the man is wrong, FreeBSD look at LD_LIBRARY_PATH before rpath. So, when LD_LIBRARY_PATH contains /lib:, it crashes as seen in this thread. The test program picks the wrong lib libgcc_s ! Not a GCC bug then :-) Do you agree ? (I don't get why O3 makes program requiring the last libgcc_s, I'll expect it to be required regardless of optimization level)
