Previously it would erroneously turn off all warnings. +.PP +This bug fix may cause some programs to start correctly issuing warnings. +.SS "Remove over-optimisation" +.IX Subsection "Remove over-optimisation" +Perl 5.8.4 introduced a change so that assignments of \f(CW\*(C`undef\*(C'\fR to a +scalar, or of an empty list to an array or a hash, were optimised away. As +this could cause problems when \f(CW\*(C`goto\*(C'\fR jumps were involved, this change +has been backed out. +.SS "\fBsprintf()\fP fixes" +.IX Subsection "sprintf() fixes" +Using the \fBsprintf()\fR function with some formats could lead to a buffer +overflow in some specific cases.

The resulting object code and the +\&\f(CW\*(C`perl\*(C'\fR binary may well be smaller than 5.8.7, in particular due to a change +contributed by Dave Mitchell which reworked the warnings code to be +significantly smaller. Apart from being smaller and possibly faster, there +should be no user-detectable changes. +.PP +Andy Lester supplied many improvements to determine which function +parameters and local variables could actually be declared \f(CW\*(C`const\*(C'\fR to the C +compiler. Steve Peters provided new \f(CW*_set\fR macros and reworked the core to +use these rather than assigning to macros in LVALUE context. +.PP +Dave Mitchell improved the lexer debugging output under \f(CW\*(C`\-DT\*(C'\fR +.PP +Nicholas Clark changed the string buffer allocation so that it is now rounded +up to the next multiple of 4 (or 8 on platforms with 64 bit pointers).
