I'm having nearly the same problem. Running glibc2.1.2 on
an SMP machine. Adding a printf
before the dlopen() call in dlopen_dll() and running with
LD_BIND_NOW=1 and LD_DEBUG=files,libs,reloc,versions
produces:
dlopen_dll: 'libshell32.so'

So, we try to dlopen libshell32.so and dlopen() calls the init
routine for that library. In the init routine, Wine tries to
load all the libraries that this one depends on. So, in this
case, it tries to dlopen libole32.so. It crashes
and launches the debugger (notice the pid in the left column
changes). I've also seen the problem with libversion.so loading
liblz32.so. In that case the stack backtrace is slightly
different (crashes in a different place), but I don't think
its too important.
So, is dlopen() supposed to be reentrant? If not, we have a
problem.
