Hi all!
I'm new to this list, but have used Valgrind many times in the past.
Today I'm making a serious effort to clean up a non-trivial body of code, and
have run into a number of error reports like this one:
==00:00:00:11.329 1533== Conditional jump or move depends on uninitialised
value(s)

==00:00:00:11.329 1533==
The problem with that report is that line 231 contains no explicit code:
static HS_IF_STATE HS_send2HS (HS_out_thread * myoutthr,
HS_MSGBUF * msgbuf,
HS_IF_PARMS * ifparms,
xmlChar * xmlbufptr,
char * HS_resp,
HS_patdat * patdat,
char * databuf)
{
<== line 231
HS_IF_STATE status = OK;
int success, warnings;
int numtries = 0
I can't find anything that's allocated in that function that would be
un-initialized later in the program, and I don't know what it thinks is on line
231.
Advice will be appreciated, thanks in advance!
