Hi hackers, I've read in this blog ( http://big-elephants.com/2015-10/writing-postgres-extensions-part-i/) and I wrote an extension about base36_encode with c code but when I executed a query like this below I got a warning below.
``` postgres=# SELECT base36_encode(123); WARNING: problem in alloc set ExprContext: detected write past chunk end in block 0x55fb75334d40, chunk 0x55fb75334d68 WARNING: problem in alloc set ExprContext: detected write past chunk end in block 0x55fb75334d40, chunk 0x55fb75334d68 base36_encode --------------- 3f (1 row) ``` I don't know what this warning means and how I can fix it. Thanks Dong Wook Lee.
