assertion

assertion

[Karl]

I'm seeing the following error running the iozone bench mark program with the 
-a option from a network drive ( z/OS running the SMB server).The iozone
executable is located in the root of the filesystem. If I execute one directory
into the filesystem, I do not encounter the assert.
Z:\>iozone -a
assertion "root_idx != -1" failed: file "/ext/build/netrel/src/cygwin-1.7.1-1/wi
nsup/cygwin/mount.cc", line 363, function: void mount_info::init()

What does this error mean?

It means you are using an old version of cygwin.  If you upgrade (the 
current version of cygwin1.dll is 1.7.7), the bug will be gone.
