Hi!
Using latest polipo git version
(b92db574c11961f681fa258314bd7470e4449cc0), with the following patch
(kindly provided by Juliusz; for a specific situation I need that all
the HTTP requests are sent with Pragma: no-cache), I saw that polipo
was crashing.
diff --git a/server.c b/server.c
index d59d772..c9ce192 100644
--- a/server.c
+++ b/server.c
@@ -1653,7 +1653,8 @@ httpWriteRequest(HTTPConnectionPtr connection, HTTPRequest
}
n = httpPrintCacheControl(connection->reqbuf, n, bufsize,
- alwaysAddNoTransform ? CACHE_NO_TRANSFORM : 0,
+ ((alwaysAddNoTransform ? CACHE_NO_TRANSFORM : 0)
+ CACHE_NO),
&request->cache_control);
if(n < 0)
goto fail;
A gdb output is attached (I hope that it helps).
Also, I am seeing a lot of this in polipo's logfile (with the default
0x7 value):

What could be causing this, please?
Thank you very much!
