FreeBSD 10.0 amd64
tinyxml2-20140124
gcc version 4.7.4 (FreeBSD Ports Collection)

Linking to tinyxml2 dynamically causes a segmentation fault when I run a program:
[OUTPUT]
$ g++ test.cpp -o test -ltinyxml2
$ ./test test.xml
Segmentation fault (core dumped)
[/OUTPUT]

I can link to it statically without encountering the same problem:
[OUTPUT]
$ g++ test.cpp -o test /usr/local/lib/libtinyxml2.a
$ ./test test.xml
Loading XML contents....

[/OUTPUT]

NOTE: This also seems to affect textproc/tinyxml, though I have not tried statically linking yet.
