This can be seen when evalling: (eq [] []) ; Evalutes to t (eq [1 2 3] [1 2 3]) ; Evaluates to nil - After read1 creates the zero_vector, it sets bits in the size field to indicate it is a PVEC_COMPILED pseudo vector - The global zero_vector is thereafter a PVEC_COMPILED pseudo vector, including the empty vector of the font data - Later, the font_list_entities function checks the size of the font data vector using ASIZE. It does not expect a pseudo vector, so it makes no such checks. - Because the pseudo vector bits are set, the size is very large - Indexing too far into the font data vector results in a core dump What should the behavior be? Perhaps (eval #[]) should evaluate to [] instead of #[]? Maybe an eassert in font_list_entities that its vector is not a pseudo vector couldn't hurt either?

I.e. if empty bytecode strings are never produced by the bytecomp and never used otherwise, shouldn't we just disallow #[] object, like we disallow an integers too large (or too small) for Lisp_Object?

Of course, this is technically possible. <IMHO> But I don't see a reason for this at all.

How many different zero vectors do we need? We at least need 2 (the [] and the #[]), but do we need others? If not, let's try and change the code so that we can have those two pre-allocated and use the right one at the right place. Stefan ^ permalink raw reply [flat|nested] 32+ messages in thread
