Attached is the test file for a proposed new defect macro,
This identifies compilers (such as Borland) that do not always convert
expressions to bool as required by 5.14/5.15 and elsewhere. The
workaround is fairly simple - detect the bad compiler and add an
additional static_cast<bool>( ) around the (sub)expression.
This only really catches classes relying on the
The test results I am posting have applied this workaround in a number
of places, and obviously I would prefer to post those patches with a
defect macro rather than compiler (and version) specific workarounds.
Note: the tests checks all 'boolean contexts', not just the two or
three that fail with Borland. I don't know if this will catch any
As ever, I am open to suggestions for a better name.
