[Bug 785318] [NEW] programs segfault trying to dlopen libQtOpenGL

[Stew Benedict]

Public bug reported:

This originally surfaced in LSB testing (lsblibchk) and a similar bug
was reported against Debian

ref:
http://bugs.linuxbase.org/show_bug.cgi?id=3233
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=518131

The test case attached in the Debian bugs illustrates the problem:

stew at ubuntu-latest-32:~$ gcc -o dltest -ldl dltest.c
stew at ubuntu-latest-32:~$ ./dltest /usr/lib/libQtOpenGL.so.4
libQtOpenGL.so.4      libQtOpenGL.so.4.7    libQtOpenGL.so.4.7.2
stew at ubuntu-latest-32:~$ ./dltest /usr/lib/libQtOpenGL.so.4
opening /usr/lib/libQtOpenGL.so.4...
closing /usr/lib/libQtOpenGL.so.4...
Segmentation fault

This appears to be unique to Ubuntu (for libchk anyway), I'm not having
issues on other distributions with the same version of Qt.
