:

SvUPGRADE() is no longer an expression. Originally this macro (and its underlying function, sv_upgrade()) were documented as boolean, although in reality they always croaked on error and never returned false. In 2005 the documentation was updated to specify a void return value, but SvUPGRADE() was left always returning 1 for backwards compatibility. This has now been removed, and SvUPGRADE() is now a statement with no return value.

So this is now a syntax error:

if (!SvUPGRADE(sv)) { croak(...); } 

If you have code like that, simply replace it with

SvUPGRADE(sv); 

or to to avoid compiler warnings with older perls, possibly

(void)SvUPGRADE(sv); 

이미 reported을하고있다.
