Browsing the w3c-libwww source code, it looks like if READDIR_R_3 is defined (because --enable-reentrant is used) the stack will get corrupted. Both HTFile_readDir() and HTMulti.c's dir_matches() allocate "struct dirent result;". The buffer needs to be bigger. The IRIX man page says: ... The storage pointed to by entry shall be large enough for a dirent with an array of char d_name member containing at least {NAME_MAX} plus one elements. If you pass something sizeof(struct dirent) then readdir_r will write off the end of it when processing any non-trivial filename.
