Hi Ilya\,

You mentioned "esoteric" ways to corrupt the sv arena and I think I have found one although I don't know enough of the perl internals to know if that is the real cause​:

      \.\.\.

my %prelim_conf; tie %prelim_conf\, 'FOCS'\, $global_conf; # untie %prelim_conf; undef %prelim_conf;

exit 1;

(I added then commented out the untie call) Seems that if you tie a variable then undef it without untying it you cause damage to whatever you tied to. In this case the actual damage occurs during the exit operation so I assume that some sort of cleanup is done at that level on a corrupted global_conf. Does that sound plausible ?

thanks\,

bruno.
