Inexplicable ASAN report. Code generation bug?
...happens with
-O2 and not when I remove the -O flags which makes it hard to debug
and makes me suspect it's dependent on exactly which instructions the
code generation decides to access the bytes involved. Afaict the C
code shouldn't be accessing the poisoned bytes.
The report looks like:
init_var_from_num: NUMERIC (short) w=0 d=1 POS 6 bytes: 18 00 00 00 80 80
