btFullAssert ( yadda_yadda ) ;
...in the btScalar.h header, it's defined as:
#define btFullAssert
...which means that the statement above becomes:
( yadda_yadda ) ;
...which means that code may actually be compiled and executed (unnecessarily) - and even when the code is something simple like:
( i > 0 && i < 3 ) ;
...the GCC tosses out a 'statement with no effect' warning - before
it optimises away the code.
The fix is:
#define btFullAssert(x)
...so that the macro still takes a parameter which is now removed
from the sources so you get:
;
...which is guaranteed not to generate code.
