Getting the value of the x variable on the file corresponding to the below ncdump output
with -fsanitize=undefined raises
ncx.c:1034:14: runtime error: left shift of 128 by 24 places cannot be represented in type 'int'
This is due to *cp being promoted to int before doing the left shift, instead
of the intended unsigned. So do the cast to unsigned internally rather than
externally
ncdump file to reproduce:
netcdf temp {
dimensions:
x = 2 ;
y = 2 ;
v = 2 ;
variables:
int x(v) ;
byte y(y, x) ;
data:
x = _, _ ;
y =
-127, -127,
-127, -127 ;
}
