Strange. I know you are not very interested in debugging user-specific 
bespoke executables and I know that providing a test case would be 
ideal, but an executable that has built and executed here successfully 
under Cygwin [1.5] for the last nn years, fails in [1.7] with the message

$ ./this_is_the_user_executable.exe
assertion "root_idx != -1" failed: file 
"/netrel/src/cygwin-1.7.0-61/winsup/cygwin/mount.cc", line 363, 
function: void mount_info::init()

Crazy I know, but is there anything obviously wrong (or recently 
changed) with mount.cc at your end? I'm using Windows 7 build 7600. 
Thank you.

Fergus
