[Libevent-users] Re: OpenSSL support and Crash in COMP_CTX_free on Mac OS X?

[Jeffrey Walton <noloader@xxxxxxxxx>]

So it appears this issue is related to Mac OS X not honoring an RPATH.
I compile and link against OpenSSL 1.0.1e, but OS X dylinks OpenSSL
0.9.8.

I built libevent against OpenSSL 1.0.1e via -I and  `-L`. I built my
program against OpenSSL 1.0.1e via -I and -L. including LDFLAGS of
`-Wl,-rpath /usr/local/ssl/darwin`.

When I look at it under the debugger:

(gdb) file ./ac-test.exe
(gdb) b main
(gdb) r
...
(gdb) info shared
The DYLD shared library state has been initialized from the
executable's shared library information.  All symbols should be
present, but the addresses of some symbols may move when the program
is executed, as DYLD may relocate library load addresses if necessary.
