Hello,
Trying to upgrade Sage to 9.5 on FreeBSD, I'm encountering an infinite
loop in doc-inventory--reference-manifolds.
When investigating for this problem (not yet solved), I noticed several
warnings in sagelib / ginac when compiled with clang:
sage/symbolic/ginac/cmatcher.cpp:548:17: warning: code will never be executed
[-Wunreachable-code]
ret_val = false;
^
sage/symbolic/ginac/cmatcher.cpp:761:17: warning: code will never be executed
[-Wunreachable-code]
ret_val = false;
^
sage/symbolic/ginac/numeric.cpp:981:9: warning: code will never be executed
[-Wunreachable-code]
setflag(status_flags::evaluated | status_flags::expanded);
^~~~~~~
sage/symbolic/ginac/numeric.cpp:4368:34: warning: code will never be executed
[-Wunreachable-code]
throw std::runtime_error("iquo: bad input");
^~~~~~~~~~~~~~~~~
sage/symbolic/ginac/numeric.cpp:4406:34: warning: code will never be executed
[-Wunreachable-code]
throw std::runtime_error("iquo2: bad input");
^~~~~~~~~~~~~~~~~~
These lines could simply be removed, unless some other behaviour was
intended?
Regards.
