For some reason I wasn't able to use sed to filter it, and just ulimit -c 0 didn't suppress it either. abrt sets the core pattern to: "|/usr/libexec/abrt-hook-ccpp /var/spool/abrt %p %s %u %c"" which apparently allows core dumps even if ulimit -c is 0, due to the pipe. Temporarily changing the kernel's core pattern to just plain "core" and setting ulimit -c to 0 does suppress it. These are reset to original values after the test is run.
