Hello,
in the current master head (4cbe3ac3e86790d05c569de4585e5075a62a9b41),
I've noticed the compiler warnings in src/backend/utils/mb/conv.c
conv.c: In function ‘UtfToLocal’:
conv.c:252:23: error: ‘iutf’ may be used uninitialized in this function
[-Werror=maybe-uninitialized]
...
conv.c: In function ‘LocalToUtf’:
conv.c:301:23: error: ‘iiso’ may be used uninitialized in this function
[-Werror=maybe-uninitialized]
...
The compiler doesn't know that the 'l' may varies between 1 and 4. Hot
fix may be:
1. preinitialize it
2. delete last if statement (change else-if to else)
3. change it to switch-case and set default behaviour
Regards,
Karol
