The pattern contains, without leading / trailing slahes: \Q\ \E The core pattern is one backslash and one space each. > This is the interesting part: size = sizeof(REAL_PCRE) + (length + > cd->names_found * cd->name_entry_size) * sizeof(pcre_uchar); > > Could you print sizeof(REAL_PCRE), length, and size here? 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?
