I'm debugging a modification to Cactus, and something I've done has
tripped an assertion error when running the RK2-central.par test. The
TestMoL_InitVars: Assertion `cctki0_ialn>0' failed.
The variable cctki0_ialn seems to get filled in from
cctkGH->cctk_alignment, which is (as far as I can see) only set in
mode.cc by carpet.
The test in question, however, uses PUGH.
Valgrind confirms that just before the assertion error, I am tripping a
conditional depends on uninitialized value error. However, I don't see
this same problem when running with the unmodified Cactus source--so
somehow I've broken something relating to this infrastructure.
How and where is cctk_alignment supposed to get set when running PUGH?
What should its value be? Thanks.
