Description

Blast fails with exception
ZZZ: Exception: Failure("SMT sovler answer is strange: Error: Undefined name \"-1073741824\".")
on the attached driver.

Command line:
LDV_DEBUG=100 BLAST_EXP_NOALIAS=1 RCV_TIMELIMIT=900 RCV_MEMLIMIT=1800000 BLAST_SOLVER=yices BLAST_OPTIONS="-devdebug" ldv-manager tag=current envs=linux-2.6.31.6.tar.bz2 drivers=wl12xx.ko.tar.bz2 "rule_models=32_7"

If comment the following line in spi.c then the result will be unsafe.

void wl12xx_spi_read(struct wl12xx *wl, int addr, void *buf,
            size_t len)
...
   //cmd |= WSPI_CMD_READ;
