The pattern contains, without leading / trailing slahes:
\Q\ \E
The core pattern is one backslash and one space each.

After this line, the numbers are as follows:
sizeof(REAL_PCRE) = 56
length = 13
size = 69
I now remember that I compiled with LINK_SIZE=3. Does this matter?
Yes, it does. If I recompile with LINK_SIZE=2 (the default), I get these
numbers:
sizeof(REAL_PCRE) = 56
length = 11
size = 67
Does this help?
