I have a function declared bool that is acting rather non-bool.
std::cout << obj.fn()
gives me "76" and
fails, with the message
/home/ross/peter/R/mspath/src/test/Covariates_test.cc(178): error in
"obs_covariates": test env.matchesObservation() == true failed [76 != 1]
std::cout << true
obj.fn() works OK as an argument to if (obj.fn()).
I am using g++ 1:3.3.5-5 on Debian GNU/Linux. I've tried -O2 and -O1;
same behavior either way.
boost is 1.31.0-9
The function is declared
bool matchesObservation() const
Maybe bool is being typedef'd or #define'd to int somewhere, for
compatibility with old code? Probably not; I tried printing
typeid(xxx).name() and got "b" for true and the function return value,
while I got "i" for the number 1.
I tried tracing into the code with limited success. Some mix of the
fact that the underlying libraries weren't a debug version, that the
code was optimized, and that there are #line directives (the source
files were generated out of another file) made it hard to follow.
