--- Comment #5 from Philip Hazel <ph10@???> ---
I took a quick look at the code and it's a trivial oversight bug. I've fixed it
and committed the patch. Here it is (for 10.33):

--- src/pcre2_jit_compile.c     (revision 1089)
+++ src/pcre2_jit_compile.c     (working copy)

-GETCHARINC(c, cc);
+/* Patch by PH */
+/* GETCHARINC(c, cc); */

+c = *cc++;
#if PCRE2_CODE_UNIT_WIDTH == 32
if (c >= 0x110000)
return NULL;
