Finally I made a step by step to reproduce the full report (total warnings [general analysis]: 36). Firstly, take a look at this new generated report:
https://duallsistemas.com.br/download/pvs_mhd/fullhtml2 The steps: Download the free PVS-Studio binary from: https://github.com/viva64/how-to-use-pvs-studio-free/releases Now, run the following commands: # clone MHD from trunk git clone https://gnunet.org/git/libmicrohttpd.git # enter into its folder cd libmicrohttpd/ # create the boostrap scripts ./bootstrap # configure the building environment ./configure # mark all source for analysis how-to-use-pvs-studio-free -c 2 -m src # build MHD pvs-studio-analyzer trace -- make # analyze the code pvs-studio-analyzer analyze # generate the HTML report from generated log plog-converter -a GA:1,2 -t fullhtml PVS-Studio.log -o fullhtml Now, take a look at "fullhtml" folder, you may get an "index.html" containing all reported issues (like the link I showed above). Result for my environment / MHD copy: Total messages: 47 Filtered messages: 36 I would like to help to fix those issues.
