This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "GiNaC -- a C++ library for symbolic computations". The branch, ginac_1-5 has been updated via 052f124551d2b78104b0de2008db6b8819713625 (commit) from c40c54f17b68f79ee42833adb3364970385e2caa (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- commit 052f124551d2b78104b0de2008db6b8819713625 Author: Alexei Sheplyakov <alexei.sheplyakov@gmail.com> Date: Sat Oct 9 18:39:41 2010 +0200 mul: algebraic_subs_mul(), has(): don't write beyond the end of array algebraic_match_mul_with_mul() iterates over operands of mul, that is for (size_t i=0; i<e.nops(); ++i) However, the size of arrays (`vectors' in STL speak) passed to this function is seq.size(), which is nops() - 1 for any mul object. Thus algebraic_match_mul_with_mul() accesses beyond the arrays limit. Usually it's not a problem, since any reasonable implementation of std::vector<bool> packs booleans into ints (or longs). However, some STL implementations (in particular, the one shipped with msvc) are more picky, and access beyond the vector<bool> limits results in a segfault. Therefore let's play safe and allocate proper number of elements (that is, nops()) for those arrays (subsed and currsubsed).
