PATCH: [perl #134329] Use after free in regcomp.c

A compiled regex is composed of nodes, forming a linked list, with
normally a maximum of 16 bits used to specify the offset of the next
link.  For patterns that require more space than this, the nodes that
jump around are replaced with ones that have wider offsets.  Most nodes
are unaffected, as they just contain the offset of the next node, and
that number is always small.  The jump nodes are the ones affected.

When compiling a pattern, the 16 bit mechanism is used, until it
overflows, at which point the pattern is recompiled with the long jumps

When I rewrote the compiler last year to make it generally one pass, I
noticed a lot of the cases where a node was added didn't check if the
result overflowed (the function that does this returns FALSE in that
case).  I presumed the prior authors knew better, and did not change
things, except to put in a bogus value in the link (offset) field that
should cause a crash if it were used.  That's what's happening in this

But seeing this example, it's clear that the return value should be
checked every time, because you can reach the limit at any time.  This
commit changes to do that, and to require the function's return value to
not be ignored, to guard against future changes.

My guess is that the reason it generally worked when there were multiple
passes is that the first pass didn't do anything except count space, and
that at some point before the end of the pass the return value did get
checked, so by the time the nodes were allocated for real, it knew
enough to use the long jumps.

This was the result of trying to continue to parse after realizing that
we were going to have to reparse using long jumps.  This continuing only
happened when we realized we were going to have to reparse in order to
count parentheses anyway, and it was an attempt to save a pass in the
regex compiler, as without doing the continuing we'd restart the parse
to use long jumps from the beginning, and then when finished, would
restart the parse to count the parentheses.

However, in most cases this doesn't help, as when we get towards the end
of the parse (as in the test case in this ticket), we need the long
jump, and will segfault because we don't have it.  So we need the extra

Make find.t work on VMS by trimming trailing dots.

GSMATCH in the linker options file tells the image activator
whether a dynamic library being loaded is compatible with what it
originally linked against.  Ideally we would like to encode the
version number and all the options that can make a build binary
incompatible with another build of the same version, but there
are about 30 such options and only 8 bits (on Alpha) in which to
store both the version number and the options.

We've lived with only 3 bits reserved for 3 options, but as of
version 32 of Perl 5, we'll need 6 bits for the version number:

    $ perl -e "$v = 31; printf('%b', $v);"
    $ perl -e "$v = 32; printf('%b', $v);"

leaving us only 2 bits for options.

defined in the environment.
