I can run python -c 'import _wp,sqlite3' and see Python abort, but if I swa= p the module order, everything seems to be fine. gdb is useless if I wait until it breaks, but if i set a breakpoint on cygwin1!abort beforehand, I get this s= tack: (gdb) where #0 abort () at /usr/src/debug/cygwin-1.7.22-1/winsup/cygwin/signal.cc:362 #1 0xc3b05111 in cyggcc_s-1!__deregister_frame_info_bases () from /usr/bin/cyggcc_s-1.dll #2 0x65fc10e2 in __gcc_deregister_frame () from C:/users/dancol/wptools/_w= p.dll #3 0x610265f5 in run_dtors (this=3D) at /usr/src/debug/cygwin-1.7.22-1/winsup/cygwin/dll_init.cc:80 #4 run_dtors (this=3D) at /usr/src/debug/cygwin-1.7.22-1/winsup/cygwin/dll_init.h:72 #5 run_dtors (this=3D) at /usr/src/debug/cygwin-1.7.22-1/winsup/cygwin/dll_init.cc:41 #6 dll_global_dtors () at /usr/src/debug/cygwin-1.7.22-1/winsup/cygwin/dll_init.cc:52 Does that help at all?
