0002117: frama-c gets confused by comma operator inside ternary operator: cannot cast from void to char
GCC and Clang correctly parse and compile the testcase below, however frama-c considers it invalid (cannot cast from void to char). In (char)(1?(((x)=6),1):0) AFAICT the type of (((x)=6),1) is integer, the void on the lhs of the comma operator should be ignored.
$ cat >x.c <
$ frama-c --version Version: Sodium-20150201 Compilation date: Thu May 7 22:46:49 EEST 2015 Share path: /home/edwin/.opam/system/share/frama-c (may be overridden with FRAMAC_SHARE variable) Library path: /home/edwin/.opam/system/lib/frama-c (may be overridden with FRAMAC_LIB variable) Plug-in paths: /home/edwin/.opam/system/lib/frama-c/plugins (may be overridden with FRAMAC_PLUGIN variable) $ ocaml -vnum 4.01.0 I originally encountered this problem when trying to parse sqlite3 with frama-c, see the getVarint32 macro.
