[Valgrind-users] Helgrind doesn't handle bit field correctly

[Will D. <wy...@ca...>]

Hi,

In our application, we use bit fields a lot. For example:

class data {
unsigned int the_thread_1_data:1;
unsigned int the_thread_2_data:3;
...
};

When one thread is writing to the_thread_1_data, and another thread is reading or writing to the_thread_2_data, helgrind will flag racing condition. Is this a known issue in helgrind? Is there a way to get around this? I believe the operation is multithread safe.

Thanks,
