match() recursively, but this ran substantially slower. The current version is
a refactoring that uses a vector of frames to remember backtracking points.
This runs no slower, and possibly even a bit faster than the original recursive
implementation. An initial vector of size START_FRAMES_SIZE (enough for maybe
50 frames) is allocated on the system stack. If this is not big enough, the
heap is used for a larger vector.
implementation.
At first, an initial vector of size START_FRAMES_SIZE (enough for maybe 50
frames) was allocated on the system stack. If this was not big enough, the heap
was used for a larger vector. However, it turns out that there are environments
where taking as little as 20KiB from the system stack is an embarrassment.
After another refactoring, the heap is used exclusively, but a pointer the
frames vector and its size are cached in the match_data block, so that there is
no new memory allocation if the same match_data block is used for multiple
matches (unless the frames vector has to be extended).
