+STACK SIZE IN WINDOWS ENVIRONMENTS
+
+The default processor stack size of 1Mb in some Windows environments is too
+small for matching patterns that need much recursion. In particular, test 2 may
+fail because of this. Normally, running out of stack causes a crash, but there
+have been cases where the test program has just died silently. See your linker
+documentation for how to increase stack size if you experience problems. The 
+Linux default of 8Mb is a reasonable choice for the stack, though even that can 
+be too small for some pattern/subject combinations. There is more about stack 
+usage in the "pcrestack" documentation.

 COMMENTS ABOUT WIN32 BUILDS
 
 There are two ways of building PCRE using the "configure, make, make install"
