Hello list,

Has anyone heard of cmsfscat or cmsfslst corrupting a CMS disk?  A few of
us were sharing a common 191 disk R/W occasionally on CMS, but R/O on
Linux (by definition).

I ran a script that uses cmsfs and got this:

cmsfs_map_ADT(): directory RECFM 'V' not 'F'
cmsfs_vopen(): cmsfs_map_ADT() returned -1
*** glibc detected *** cmsfscat: double free or corruption (!prev):

Now the common CMS disk is giving a "device error". Not sure if this is
the cause or the symptom. Any help will be appreciated.
