You discovered a bug in pcre.sl.  Here is a patch:

diff --git a/modules/pcre.sl b/modules/pcre.sl
index fc062f4..b9ef467 100644
--- a/modules/pcre.sl
+++ b/modules/pcre.sl
@@ -25,7 +25,7 @@ Qualifiers:\n\
    if (typeof (re) != PCRE_Type)
      {
        variable compile_options = qualifier ("options", 0);
-       re = pcre_compile (re, options);
+       re = pcre_compile (re, compile_options);
      }

Also note that the calling syntax you want is:

  str = pcre_matches(".*", str; options=PCRE_DOTALL);

Thanks,
