This message is output in _gcry_mpi_const of WebKitBuild/DependenciesGTK/Source/libgcrypt-1.7.6/mpi/mpiutil.c.

This means _gcry_mpi_init doesn's seem to be called.
_gcry_mpi_init is called from global_init of libgcrypt-1.7.6/src/global.c.
global_init has this comment.

gcry_check_version() needs to be called to initialize at startup.

WIP patch

This WIP patch solves the crashes. But, two problems.

* I'm not sure this is the right place to call gcry_check_version().
* Solved Crash problem. But, the test cases still Failed. I think Bug 169272 looks the same.

Zan, do you have any idea?

[Zan Dobersek]

Yes, libgcrypt has to be explicitly initialized. Otherwise the test relies on being run after other tests that force through the necessary initialization.

I'm handling this in bug #173589.

The ec_importKey.worker.html and test_ec_importKey.https.html tests still fail due to missing implementations. TestExpectations address that, but not the crashes.

[Fujii Hironori]

Thank you. Closed this bug.
