Hi,

src/pcre2_jit_compile.c:13746
        re = 0x0
        functions = <optimized out>
        executable_allocator_is_working = 1


It looks like you call the jit compiler with a NULL regex (probably after a
failed compilation).

I checked the code:

#ifdef SUPPORT_JIT
executable_functions *functions = (executable_functions *)re->executable_jit;
static int executable_allocator_is_working = 0;
#endif

if (code == NULL)
return PCRE2_ERROR_NULL;

It looks like the "code==NULL" check happens after re->executable_jit is read.
This is clearly wrong. Could you reverse these two statements and try what
happens?
