Despite using PCRE2_MATCH_INVALID_UTF flag in pcre2_compile, is it possible for the application to crash for invalid input subject(non-UTF inputs)?

See more:

C++

My patterns are valid UTF encoded and the input subjects may or may not be valid UTF,the application worked fine for UTF formatted subjects and crashed for Big5 and ISO-8859-1 subjects during matching.

The above site suggested on using flag PCRE2_MATCH_INVALID_UTF during compile time but it didnt work for me.

So does PCRE2 really work without crash when compiled with PCRE2_MATCH_INVALID_UTF flag?

What I have tried:

My sample code:

int rc;
pcre2_code *re;
pcre2_match_data *match_data;
pcre2_match_context *mcontext;
pcre2_jit_stack *jit_stack;

re = pcre2_compile(pattern, PCRE2_ZERO_TERMINATED, PCRE2_MATCH_INVALID_UTF,
&errornumber, &erroffset, NULL);
rc = pcre2_jit_compile(re, PCRE2_JIT_COMPLETE);
mcontext = pcre2_match_context_create(NULL);
jit_stack = pcre2_jit_stack_create(32*1024, 512*1024, NULL);
pcre2_jit_stack_assign(mcontext, NULL, jit_stack);
match_data = pcre2_match_data_create(re, 10);
rc = pcre2_jit_match(re, subject, length, 0, 0, match_data, mcontext);//Application crashes here for invalid UTF subjects

pcre2_code_free(re);
pcre2_match_data_free(match_data);
pcre2_match_context_free(mcontext);
pcre2_jit_stack_free(jit_stack);
