SCO 3.2v4.2 + GNU gcc 2.7.2.1
If it is initialized to zero so why is this code needed at all:
--- line 194 of ssl_gcachecommon.c of mod_ssl-2.0.11-1.3.2
static int nCalls;
if (++nCalls == 1) {
nCalls = 0;
ExpireCache();
}
---
I see no meaning of this if-thing there at all?
I don't know about the GCC static variable initializing stuff but fact
is that when I uncommented the if clause from there the gcache started
to expire cahce correctly.
