[buildd-tools-devel] Bug#637931: results obtained with the perl debugger

[Michael Karcher]

Some hints to the reported bug: I ran the perl debugger on Adrian's
machine investigating the issue a bit, but did not do a full
investigation. This is what I came up with:

The download step crashes (i.e. the exec dies) at the point the
"downloading" message is printed to to stdout (Utility.pm:206), because
$stdout is undef at that point. It has been set to undef by the
preparation of the download restoring $stdout from $saved_stdout, the
latter being undefined. A breakpoint to open_log which should initialize
$saved_stdout did not trigger, so open_log was not called.

I did not investigate further why there was no call to open_log.
