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?
