+ applications where each thread has a very small stack. From release

+At first, an initial vector of size START_FRAMES_SIZE (enough for maybe 50

+This program tests the POSIX wrapper to the PCRE2 regular expression library.
+The main PCRE2 test program is pcre2test, which also tests these function
+calls. This little program is needed to test the case where the client includes
+pcre2posix.h but not pcre2.h, mainly to make sure that it builds successfully.
+However, the code is written as a flexible test program to which extra tests
+can be added.
+
+Compile with -lpcre2-posix -lpcre2-8
+
+If run with no options, there is no output on success, and the return code is
+zero. If any test fails there is output to stderr, and the return code is 1.
+
+For testing purposes, the "-v" option causes verification output to be written
+to stdout. */

- A fixed stack space can be allocated for local variables

Disadvantages:
- - No automatic register allocation, and temporary results are
