Couldn't reproduce on Linux with ICU 3.6. This place:

#1  0x00000000005407c1 in zif_collator_get_locale (ht=1, 
return_value=0xd7b008, return_value_ptr=0x0, this_ptr=0xd7b088, 
return_value_used=1,
    tsrm_ls=0x0) 
at /usr/home/felipe/php5/ext/intl/collator/collator_locale.c:52
#2  0x0000000000863fe5 in zend_do_fcall_common_helper_SPEC 
(execute_data=0x10e8088, tsrm_ls=0xd456c0) at zend_vm_execute.h:315

looks strange - how comes tsrm_ls becomes 0? It's engine code, not extension code, so I'm afraid there's some problem in the build maybe?
