Description

The integrity testing cycle reports an irreproducible error from the semispace GC.
Here are the error info:

Exit code: 134 Err: java: /home/laichunrong/harmony.regularcc/infra/build/checkouts/hdk/working_vm/vm/gc_gen/src/semi_space/sspace.cpp:309: sspace_reset_after_collection: Assertion `0' failed.

Signal reported: ABORT

Registers info is absent

I checked the code and saw some comments below

/* Check if sspace has no enough blocks to hold tospace. */
if( sspace->tospace_first_idx - sspace->first_block_idx <= num_tospace_blocks )

{ /* this case shold never happen right after minor collection, might happen after nos_boundary adjusted */ assert(0); num_tospace_blocks = (sspace->tospace_first_idx - sspace->first_block_idx) >> 3; num_fromspace_blocks = sspace->num_managed_blocks - num_tospace_blocks; }
