>Description:
With the rpm4 port (rpm-4.9.1.2), import the rpm module in python causes a segfault.

The cause of the segfault is dereferencing glob_t.gl_pathv at line 629 in rpm-4.9.1.2/rpmio/rpmfileutil.c.

The reason for the gl_pathv is set to an invalid pointer is because rpm is using the header file rpm-4.9.1.2/misc/glob.h which defines a different glob_t structure then the one found in /usr/include/glob.h.  As the glob function linked to is the one in libc.a and not misc/glob.c, resulting in dereferencing the wrong address.


>How-To-Repeat:
install rpm4 port.  run python -c "import rpm"
>Fix:
Replace the definition of the glob_t struct in misc/glob.h with the definition found in /usr/include/glob.h
