Disable PL_sawampersand
...
The problem in perl.h:
#ifndef PERL_SAWAMPERSAND
# define PL_sawampersand \
(SAWAMPERSAND_LEFT|SAWAMPERSAND_MIDDLE|SAWAMPERSAND_RIGHT)
#endif
pp_hot.c and others:
Unneeded conditionals, as PL_sawampersand is now always true.
if ( RX_NPARENS(rx)
|| PL_sawampersand
|| (RX_EXTFLAGS(rx) & (RXf_EVAL_SEEN|RXf_PMf_KEEPCOPY))
and the bodies are now always executed, despite the costly computation
of the other checks.
To my untrained eye this looks like PL_sawampersand is now always enabled,
and not replaced by cow.
