Why do you think it doesn't release it? Your QRegularExpressionMatch object 
goes out of scope at the end of the block and, unlike QRegExp, executing a 
match in QRegularExpression does not modify it (except for compiling / 
optimising the the pattern).

An increase in addressable virtual memory is expected; an increase in total 
memory allocation is acceptable, but not a leak of memory.

So I have to ask: how did you measure?
