:)
And I hoped a programmer who knows the source could find out and fix
very quickly.
To be honest - I did not investigate the reason for the failure as
there were other things on my todo list.
Well after getting some sleep I will check that again.

Nevertheless here are the stack traces again - in case someone else can
identify the cause in the meantime:

warning: Hit beginning of text section without finding
warning: enclosing function for address 0x8
This warning occurs if you are debugging a function without any symbols
(for example, in a stripped executable).  In that case, you may wish to
increase the size of the search with the `set heuristic-fence-post' command.

Otherwise, you told GDB there was a function where there isn't one, or
(more likely) you have encountered a bug in GDB.
