I met a strange problem recently. The __STATIC_CONSTRUCTOR() calls are not in proper order.
I have one shared object file (im-scim.so), and it depends on another shared library file (libscim-1.0.so). In im-scim.so, there is a static object instance, and it calls a global function in libscim-1.0.so, in that global function, it relies no another static object instance. I wrote a small test program, it just uses dlopen() to load im-scim.so. >From the debugger, I could see, the static constructor in im-scim.so is called >before the static constructor in libscim-1.0.so. There, the test program cores. I want to know how the static constructor chain are handled? And it could be a bug of libCrun or ld.so? P.S., when I am using snv_62, the shared objects works fine, but failed on snv_66.
