Hello! I am trying to build GiNaC-1.1.6 on Alpha machine running Linux. Compilation passed without any errors, but... ~/build/GiNaC-1.1.6 $ make check [huge snip] GiNaC will now take an exam with specific input (like a pupils' exam): examining several historic failures just out of paranoia................ passed examining consistency of numeric types...... passed examining power laws..... passed examining consistency of symbolic functions.... passed examining consistency of nestedsums functions.............................................................../exams.ref exams.out differ: char 240, line 10 FAIL: run_exams ~/build/GiNaC-1.1.6 $ cat check/exams.out ----------several historic failures: (no output) ----------consistency of numeric types: (no output) ----------power laws: (no output) ----------consistency of symbolic functions: (no output) ----------consistency of nestedsums functions: Internal error: statement in file real/elem/cl_R_mul.cc, line 38 has been reached!! Please send the authors of the program a description how you produced this error! I've tried to build some simple programs, some of them work fine, but most produce the same error message or just a plain segfault. Any ideas? P.S. Some info about OS, compiler, etc. OS: Debian GNU/Linux 3.0 (a.k.a "woody") g++ version: 3.0.4 CLN version: 1.1.5, was configured with: CXXFLAGS='-O2 -g -fno-exceptions' ./configure --with-gmp --prefix=~/inst GiNaC was configured with: CXXFLAGS='-O2 -g' ./configure --prefix=~/inst
