Here it seems (if gdb gives the right value) that the data has size 4294967292
which explains that aborting of new().
Either the SI data is somehow broken, or this is a bug in libsi.
It would be great if I had the original data in a binary file. Does someone
know an elegant way to convert the printout below to a binary file, or to
save it directly from gdb?
The EIT comes from a channel with network id 133, transport stream id 3,
service id 17. This seems to be Premiere Sport 1 or F1 Konferenz. Do you have
a Premiere subscription?
