GCC seems to lose track of possible output lengths of the first sprintf() when computing possible lengths of the second. ../mbbioDirectTest.c:44:26: warning: ‘.B’ directive writing 2 bytes into a region of size between 1 and 40 [-Wformat-overflow=] 44 | sprintf(field,"%s.B%X", rec, i);

/* Theory of Operation
|
|
*
|
|
* For each of the two soft device supports (soft/raw soft/soft),
|
|
* there is a combination of mbboDirect -> val / sim -> mbbiDirect.
|
|
*
|
|
* The intermediate records are of type double (val) and long (sim) to
|
|
* check conversion from/to double.
|
|
*
|
|
* For each device support, the following is done:
|
|
* 1. The mbboDirect record is set to a specific value through the database.
|
|
* 2. The initial value is checked on both ends.
|
|
* 3. Two single bits (5 & 31) are toggled, values checked on both ends.
|
|
* 4. Sim mode is activated, one bit (0) is toggled, values are checked,
|
|
* data path (old value in val, new value in sim) is checked.
