Therefore check if integer_content() is really an integer (and if it's not just return 1, GCD for polynomials over a field is defined up to arbitrary element of the field). This fixes possible segfault when computing GCD of polynomials over rationals (this is not theoretical, see the added test case). Thanks to Ernst Moritz Hahn for reporting this bug. (cherry picked from commit 3d09388a8ea144a19949c216fae43ccba92e47aa) ----------------------------------------------------------------------- Summary of changes: check/bugme_chinrem_gcd.cpp | 18 ++++++++++++++++-- ginac/polynomial/mgcd.cpp | 10 ++++++++++ 2 files changed, 26 insertions(+), 2 deletions(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations
