Do you have a small testcase for this? (That fails on 1.1.4)

If you are working with the svn version of mono, you can use ddd to e.g.
set a breakpoint in mono_get_lmf_addr and inspect the value of
mono_jit_tls_id. If it's -1, then TlsAlloc in mini_init failed.
Otherwise I would say something is wrong with your thread support,
because TlsSetValue is called each time a thread is started by mono and
assigns each thread it's own MonoJitTlsData structure (you failed to
read in in mono_get_lmf_addr..)
BTW: You can also try and set the environment variable "MONO_NPTL".
