Initial attempt

Goblint version: heads/master-0-ge223b4f36-dirty.

Checked out git tag v.1.36.1 and executed:

autoreconf -ivf
./configure
bear -- make
goblint -v compile_commands.json

Crashes due to parsing errors in vendored SQLite (somehow not a problem in #19):

SQLite fixed attempt

The problem was caused by our redefinition of assert not accounting forSQLITE_DEBUG, which is easily fixed.

Same as above, but with

goblint -v compile_commands.json --set pre.cppflags[+] '-DSQLITE_DEBUG'

Gets past the SQLite issue but crashes due to conflicting global initializers during merging:

The two initializers are:

char *netdata_configured_host_prefix         = NULL;

char *netdata_configured_host_prefix = "";

I guess GCC is somehow fine with this and picks one of the two using whatever logic (linker arguments order?).
