0 is ok, the problem is in get_stackaddr.

exactly! For the main thread pthread_get_stackaddr returns a bull shit always
:(
But at least java 1.3 has workaround inside and handles this magic value
separatly and doesn't crash whis 3/1GB split (this value depends on TASK_SIZE
or more preciesly on current stack value aligned to some big boundary (AFAIR,
1GB)).
Anyway it's definietly a bug. I have a fix in a preloading .so library for
glibc which overrides pthread_getstack_addr symbol. If you wish I can send it
to you.
