Substituting x==log(x) in exp(x) erroneously returned log(x) because of a final subst(x==log(x)) after having eval'ed exp(log(x)) -> x. This final substitution is wrong in the general case. On the other hand, the intent is to syntactically substitute functions of a given kind etc. This patch suppresses the final top-level substitution unless the intermediate result is a container. Thanks to Burcin Erocal for reporting this bug (originally described by Kees van Schaik on sage-support@googlegroops.com). ----------------------------------------------------------------------- Summary of changes: check/exam_misc.cpp | 9 +++++++++ doc/tutorial/ginac.texi | 2 +- ginac/container.h | 24 ++++++++++++++++++++---- 3 files changed, 30 insertions(+), 5 deletions(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations
