A literal percent should be '%%' not '\%'. While '\% Layer' apparently worked
with older versions of perl, the % now starts off a placeholder in the format
string, with 'L' being a format modifier for '%a' (conversion to hexadecimal
floating point) and the 'yer' pass through, hence the output '0x0p+0yer'
%a hexadecimal floating point
q, L, or ll interpret integer as C type "long long",
"unsigned long long", or "quad" (typically
64-bit integers)
