Segmentation fault

[AlbertoDrusiani]

Hi, I'm writing my master's degree thesis and I'm using your repo to create an OCaml version of haskell-gi.
During the parsing phase, I'm encountering a segmentation fault issue, probably related to the garbage collectors.
I run some tests and segfaults comes in several different points of my code, depending on cases.

I'm attaching a gdb backtrace of one of those cases, I hope it could help.
I'm full time on my thesis in the next weeks so I'm here to help and to contribute to find the problems, thank you!

P.S: https://github.com/AlbertoDrusiani/tesi/blob/master/src/GIR/Object.ml this is one of the files that trigger the segfault, in this case is triggere by line 59
