[DVDnav-discuss] Bug report for specific DVD

[Michael Russo]

(Sorry about the reply not looking like a reply, I hadn't subscribed
to the mailing list but I am now)


I tried to define TRACE in vm.h (uncommenting the line) but I get a
message about an undefined constant FP_DOMAIN.  The compilation
succeeds without TRACE enabled.  I also can't find where this constant
is defined inside of libdvdnav.  Perhaps this is a simple oversight
related to all the cleanup work that took place in 5.0.0?

SO it crashes on the function call?

Can you define TRACE so we have more logs,please?

With my kindest regards,
