We could convert the pattern matching globals to macros that execute
code whenever the globals are accessed:
diff --git a/Src/pattern.c b/Src/pattern.c
index 72c7d97..a4fb24f 100644
--- a/Src/pattern.c
+++ b/Src/pattern.c
@@ -303,6 +303,12 @@ static long patalloc; /* size allocated for same */
static int patflags; /* flags passed down to patcompile */
static int patglobflags; /* globbing flags & approx */
+#define patflags (f(), patflags)
+void f(void)
+{
+ /* ... */
+}
+
/*
* Increment pointer to metafied multibyte string.
*/
Now, f() can assert() some invariant, or check if SIGWINCH had been
delivered (and if so, drop into a gdb breakpoint), etc...
I'm proposing this just as a means of debugging for this one problem,
not as a permanent change.
Cheers,
Daniel
