0000925: Wp rises an error in if you use struct and long long type, with wp-rte option

Description

Following command with -wp-rte option rises an error. frama-c -wp -wp-rte -wp-out wp_longlong test_wp_longlong.c Output: frama-c -wp -wp-rte -wp-out wp_longlong test_wp_longlong.c [kernel] preprocessing with "gcc -C -E -I. test_wp_longlong.c" [rte] annotating function add [kernel] The full backtrace is: Raised at file "src/kernel/command.ml", line 42, characters 10-13 Called from file "src/wp/cfgProof.ml", line 125, characters 4-118 Called from file "list.ml", line 69, characters 12-15 Called from file "list.ml", line 69, characters 12-15 Called from file "list.ml", line 69, characters 12-15 Called from file "list.ml", line 69, characters 12-15 Called from file "src/wp/cfgProof.ml", line 223, characters 1-607 Called from file "src/wp/register.ml", line 322, characters 41-57 Called from file "src/wp/register.ml", line 464, characters 3-32 Called from file "src/wp/register.ml", line 533, characters 8-20 Called from file "src/wp/register.ml", line 570, characters 4-18 Called from file "queue.ml", line 134, characters 6-20 Called from file "src/kernel/boot.ml", line 36, characters 4-20 Called from file "src/kernel/cmdline.ml", line 660, characters 2-9 Called from file "src/kernel/cmdline.ml", line 173, characters 4-8 Unexpected error (Failure("int_of_string")). Please report as 'crash' at http://bts.frama-c.com/ Note that a backtrace alone often does not have information to understand the bug. Guidelines for reporting bugs are at: http://bts.frama-c.com/dokuwiki/doku.php?id=mantis:frama-c:bug_reporting_guidelines Without wp-rte Option ok: frama-c -wp -wp-out wp_longlong test_wp_longlong.c [kernel] preprocessing with "gcc -C -E -I. test_wp_longlong.c" [wp] warning: Missing RTE guards If you use int type in INTEGER32 structure, then its ok.

Additional Information

struct INTEGER32 { // int value; // Ok long long value; // Fails }; typedef struct INTEGER32 int32; /*@ requires \valid(x) && \valid(y); */ void add (int32* x, int32* y){ int32 erg; erg.value = x->value + y->value; }

Notes
(0002144) pascal (reporter) 2011-08-12 22:21	Thanks for the report. If you are using a version of Frama-C compiled with a 32-bit OCaml compiler, you can make the error less likely by using a 64-bit OCaml compiler to recompile it. Once the bug is fixed, then you can again use any sort of OCaml compiler (32 or 64-bit).

(0002146) jessie_user (reporter) 2011-08-15 17:39	Thank you for your quick answer. I have tried ocaml64-bit compiler and it has succeeded. Unfortunately I've got another wp-plugin error with new installation.
