Instead of a segmentation fault, I'm getting an assertion failure at
src/mesa/state_tracker/st_cb_queryobj.c:100

backtrace:
#0  0x00007ffff6e79165 in raise (sig=<value optimized out>) at

Looking at both arbocclude2.c and st_cb_queryobj.c, it looks like st_BeginQuery
is missing a case for GL_ANY_SAMPLES_PASSED
