[mapserver-dev] MapCache seed fails with double free

[Rahkonen Jukka (MML)]

Hi,

The error happen a Web Mercator zoom level 14 and I am not sure if our vector tile service has some problem with creating MVT tiles, but I suppose that this double free or corruption is not normal

*** Error in `mapcache_seed': double free or corruption (out): 0x00007fd0f8002910 ***
