This change updates the
checkRegex
helper to not track symbols for a regexp when it is used by the builtinsubst
. In this case the VM will not store these matches, and therefore these symbols will not be available to the program. The compiler will, however, compile these regexp and add them to the regexp table for use by the VM, and multiple calls tosubst
are already handled by the VM.fixes: #693, fixes: #810
