Hi,

Im trying to read a JSON not very large but around 300Kb which contains a JSON array with a json string. when i try to read this json it will go out of memory. when i debug i found out the problem is from line 2107 in XSuperJSON when matching JSON field contain large data with the regex it goes out of memory, is there any workaround to fix this issue? i suspect TRegEX.Matches is not optimized and will easily eat up all the memory.

Hi,

  1. sample json to reproduce: https://drive.google.com/file/d/0B39DC6SOjOt1VUtMWkxPMzRLTW8/view?usp=sharing
  2. I tried with XE8 and 10 Seattle. both same
  3. VCL Windows

If you attempt to load attached file in 32bit application you will certainly go out of memory but in 64bit it will consume 3gb of ram to parse that JSON.
