(maybe from nm -D) Yes -- I have been using nm and objdump to examine the relevant files. The dll is called libpypy-c.dll. The symbol I want to bind to is pypy_main_startup, and its proper value (as returned by nm and objdump) is 0x6410ac60. The result I get is the value of symbol pypy_g_PyNumber_Negative (an automatically generated C function), which is 0x63443f00. I wonder if these collide in some internal hash table and the hash lookup (or the table building) is broken in some subtle way.
