__TI_resource_lock(__TI_LOCK_RAND)

Hi,

I have created a new project in CCSv6 - Version: 6.0.0.00156.

When I try to use the rand(); function the MSP430f5438a reboots when the line __TI_resource_lock(__TI_LOCK_RAND); is executed. This is because the address it's trying to jump to in the disassembly is 0x00000.

Is there something I have missed when setting up my project that creates this error?

I actually have another project where rand() works fine, and can't figure out whats different in it.

Thanks.

From rand.c v4.3.1:

_CODE_ACCESS int rand(void)
{
     int r;

     /*---------------------------------------------------------------------*/
     /* To maintain backwards compatibility with releases that do not use   */
     /* TLS, we use a mutex lock to protect accesses to the variable 'next'.*/
     /*---------------------------------------------------------------------*/
#if !defined(__TI_USE_TLS)
     __TI_resource_lock(__TI_LOCK_RAND); <---- Here
#endif

From disassembly(when I mouse over &_lock it shows _lock = 0x000000:

0117b0:   8321                DECD.W  SP
62           __TI_resource_lock(__TI_LOCK_RAND);
0117b2:   1380 2000           CALLA   &_lock
64           next = next * 1103515245 + 12345;
