Very high memory usage.

I've just upgraded from an older version of cppcheck (1.82), and the new version (1.90) uses vastly more memory than the old version.
I'm trying to analyse a project with about 850 cpp files and 1000 h files. in both cases I'm set to use as many threads as possible, analyse all #ifdef configurations and check for inconclusive errors. Using the prebuilt windows installers from the website.
v1.82 - Maximum memory usage is about 450Mbyte and grows roughly linearly as the analysis progresses.
v1.90 - Reaches 6GByte about 25% of the way through the analysis.
I have to kill the v1.90 process at that point as it starts some serious swapping to virtual memory and the system becomes unusable if it let it carry on.
Addendum - v1.83 seems to be the first version with this high memory usage.
Hello,
What command-line arguments do you pass to cppcheck? Do you use cppcheck add-ons?
No add-ons.
I'm running it through the GUI, so no clue what the command line options are.
The project file is:
<project version="1">
<platform>win32A</platform>
<analyze-all-vs-configs>false</analyze-all-vs-configs>
<check-headers>true</check-headers>
<check-unused-templates>false</check-unused-templates>
<max-ctu-depth>10</max-ctu-depth>
<includedir>
</includedir></project>
<libraries>
<library>windows</library>
</libraries>
On the preferences screen, I've got the following options checked:
General tab -
7 threads.
Force checking of all #ifdef configurations
Show "No errors found" message when no errors found.
Display error Id
Check for inconclusive errors also
Reports tab -
Save all errors when creating report
Save full path to files in reports
