Error "stack smashing detected" #36

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. run smatool -v on my Ubuntu 10.

What is the expected output? What do you see instead?
I expect to upload data to PVOutput.org.  Once there's more than 10-something 
lines of data to process, I get this :

20/8/2011 21:35:00  total=156.771 Kwh current=0 Watts togo=0 i=11 crc=3
20/8/2011 21:40:00  total=156.771 Kwh current=0 Watts togo=0 i=23 crc=3

This is caused by the PVOutput restriction of maximum 1 request per second.

I can't actually see the error since the only error that's reported is "22" (a 
Curl error meaning that there's a +400 http error).  It would be nice to use 
the curl_easy_getinfo functions to return the actual error message ...

Anyway , I've added a few "sleep(5)" statements after every curl connection to 
PVOutput.  This fixes the problem.

I still get this problem with latest sources.
I would like to fix this problem but have no idea what to search first.
Is it a libcurl mis-configuration (too small buffers?) or a problem of 
interface between smatool and pvoutput APIs?
