Remove naked pointers and Obj.truncate for compatibility with 5.00 [lablgtk2] #145

Closed garrigue closed 2 years ago

garrigue commented 2 years ago

The lookup_info structures generated by varcc were returned as raw pointers to ocaml, which caused failures in multicore. This fixes that by wrapping them, and returning them inside an allocated tuple.

(Same as #144, but for lablgtk2 this time)

Also removed Gpointer.raw_null and a call to Obj.truncate.

This versions runs without problem on 4.14 in with -disable-naked-pointers but not on multicore-5.00. We get a segfault on any linked executable, but could not track the cause.

We verified that this branch runs fine with -disable-naked-pointers on trunk too. So there is something else in multicore that causes this segmentation fault.
