Ouch. I started XWin from Windows Explorer, not thinking about setting CYGWIN=server at all. I've build my own xterm to have a debug version. Unfortunately, it doesn't happen in xterm, but in cygX11-6.dll, in function XFreeFont(), right after shmctl(id, IPC_STAT, buf) has been called. I don't have a debug version of cygX11-6 and I'm also not exactly keen to debug it. From what I can tell, the shmctl call works fine. After that call, the XFreeFont() function accesses a piece of data, 512 bytes before the address of the buffer used as third argument to shmctl(). This address (buffer - 512) results in the SEGV. Could you have another look into this? Actually I don't see anything wrong with the semctl call, it even checks the buffer pointer for being accessible.
