[pcre-dev] pcre2_jit_match(): match context needed?

[Ralf Junker]

PCRE2 pcre2jit.html:

"The fast path function is called pcre2_jit_match(), and it takes 
exactly the same arguments as pcre2_match()."

From this I concluded that I can use pcre2_jit_match() exactly as 
pcre2_match(), provided that I previously called pcre2_jit_compile().

I hence called pcre2_jit_match() without providing a match context. As a 
result, I received an AV.

Creating a match context and passing it to pcre2_jit_match() solved the 
problem.

I wondered if pcre2_jit_match() indeed needs a match context, but the 
"JIT FAST PATH API" section does not mention it.

pcre2_jit_match.c is not clear either: line 136 tests "if (mcontext != 
NULL)" whereas line 159 de-references mcontext without prior testing - 
which leads to the AV described above.

If pcre2_jit_match() indeed needs a match context, should it not return 
an error if missing (i.e. PCRE2_ERROR_JIT_BADOPTION) instead of raising 
an AV?
