|Description||I'm using OPAM 1.1.1 with OCaml 4.02.0.
I installed Frama-C using OPAM, along with its dependencies, and then tried running frama-c-gui. It segfaults. Using gdb I get the following backtrace:
Program received signal SIGSEGV, Segmentation fault.

It could be related to lablgtk. All dependencies were downloaded using OPAM (including lablgtk 2.16.0) and installed without issues.
First I tried using directly the version from OPAM, but due to the segfault error I then tried downloading the sources and compiling them myself.
When running configure, everything is ok except for "OcamlGraph 1.8.5 > 1.8.4 found: should be compatible, but no warranty. Use it at your own risk!", but I used the patch available in https://bts.frama-c.com/view.php?id=1764, and then I could run make and make install without issues. But once again, when running frama-c-gui it segfaults.
To sum up, either using OPAM or downloading and compiling the sources myself, I get the same result (unsurprisingly).
However, when switching to OCaml 4.01.0 and running "opam install frama-c", the GUI works normally.
Has the Frama-C GUI been confirmed to work with OCaml 4.02.0 already? Should I try manually compiling its dependencies to try and identify the cause of the error?|
