No luck with 0x00405AA8, but it could be in libtorrent.dll, which I will also build with debugging info. I did manage to find the following (after loading the cygwin1.dbg symbols): 0x61007038 is in dll_crt0_1(void*) (/ext/build/netrel/src/cygwin-1.7.9-1/winsup/cygwin/dcrt0.cc:974). 969 /ext/build/netrel/src/cygwin-1.7.9-1/winsup/cygwin/dcrt0.cc: No such file or directory. in /ext/build/netrel/src/cygwin-1.7.9-1/winsup/cygwin/dcrt0.cc However my Cygwin source is in /usr as opposed to /ext/build/netrel, is there a way to tell gdb to look there instead?
