You don't even need to have regex_free in your code to cause the crash
-- if you don't use the regex_compile function before using regex_find,
regex_find calls regex_compile itself, performs the find, and then calls
regex_free.
So ANY call in ANY program to regex_find without regex_compile in your
own code (or with it, but then you have to call regex_free yourself)
will cause the crash. I should have mentioned I'm using all the latest
versions of the interpreter & translator (unregistered) and am on a
WinME system. I tried compiling with both Borland & lccWin, same
result.
