Segmentation Fault on `test/zim.test.ts`

[benoit74]

We've just had two segfault on test/zim.test.ts, see https://github.com/openzim/node-libzim/actions/runs/16348986226/attempts/2

Looks like it might be correlated to #80 but no clue so opening a distinct issue since context is a bit different.

Next CI run was fine. Tend to prove this is a kind of race condition, maybe related to too early release of the content provider: #80 (comment) ; looking at StringItem code, it uses a StringProvider (see

node-libzim/src/contentProvider.h

Line 105 in f86e1ef

class StringProvider : public Napi::ObjectWrap<StringProvider> {

) which makes very little things around pointer "reservation", it just manipulate it a bit. It looks like it is highly possible the object is released before pointer is really used.
