After a bit more investigation, I hacked tsocks to spit out debug log in
its _init() function:
FILE *f = fopen( "/home/me/tsocks.msg", "a+" );
fprintf( "[%s] Hello world\n", program_invocation_name );
fclose( f );
However, when running:
$ tsocks ssh machine
Segmentation fault
The .msg file is *not* created at all!
So, it seems something is trying to initialise openSSL before calling
the _init() from tsocks...
So, I tried with another program *not* linked with openSSL. I used curl,
which is linked with GnuTLS:
$ curl https://example.com/
[works!]
Conclusion: openSSL does get initialised before tsocks. That's really weird, as
tsocks is in LD_PRELOAD,
so should come before any shared library from a NEEDED tag.
/me is now investigating the linker documentation to understand what's
goign on...
