Eric,

The entry is fine... The problem is the program that you are using to
dump the entry expects a '\0' terminated string.  If the section name is
precisely 8 characters in length, it is not a C terminated string.  The
two extra characters are actually part of the section information, the
actual section name is ".stabstr" (8 characters).

Are you linking your DLL with fixup.o?
