wine-1.1.39 and crafting station

The previous attachment was made with version wine-1.1.18-301-g014c4bf where I
can't find "context_acquire". Then I made the following modifications to
version 1.1.39 :

context = context_acquire(device, NULL, CTXUSAGE_RESOURCELOAD);
ERR("context->valid: %s\n", context->valid ? "true" : "false");
gl_info = context->gl_info;
ERR("Before ENTER_GL\n");
ENTER_GL();
ERR("Before ENTER_GL_EXTCALL\n");
GL_EXTCALL(glBindBufferARB(This->buffer_type_hint, This->buffer_object));
ERR("After ENTER_GL_EXTCALL\n");

But I don't have the same crashes with version 1.1.39. I only have crashes with
some in-game objects (crafting stations...); I don't have the crash after
login. 
What I understand is that the two crashes don't happen in the same line of
code, because here we clearly see the function returning before the crash.

What should I modify in version wine-1.1.18-301-g014c4bf to test context
validity ?
