Running the program takes Pod::Spell into and endless loop between lines 188 and 202. I stepped through with the debugger. When Pod::Spell::_treat_words is entered for the first time, $_[0] is the parser instance, $_[1] is "NAME\n\n". However, I cannot dump any other values with the x command because then the debugger aborts with »Insecure dependency in sprintf while running with -T switch at .../lib/perl5/5.10.0/overload.pm line 99«. (Just great, a core pragma is not taint-safe... groan.)

Switching taint mode off makes the listed program run normal. Can you reproduce this bug?
