This problem is caused by r191494.

The cause of the problem is: when reading PCH data, the line_table is also read
from PCH files. But the location_adhoc_data_map is not managed by GC,
thus is not read in from PCH file (only a pointer is read in).

To solve this problem, we'll need to move location_adhoc_data_map into
GC. I'll have a patch to solve this problem.
