maxima-5.29.1 is in Gentoo. Full run times of the testsuite in different
lisps on a 32-bit x86 box, and failed tests, are
sbcl-1.1.2 169
gcl-2.6.8_pre 192
cmucl-20c 213
ccl-1.8 261 rtest15 (37, 193, 196)
ecl-12.12.1 389
clisp-2.49 662
On a 64-bit x86_64 box (cmucl is not available for this platform):
sbcl-1.1.2 160
gcl-2.6.8_pre 198
ccl-1.8 273
ecl-12.12.1 389
clisp-2.49 882
All tests have passed on the 64-bit ccl-1.8, but not on 32-bit:
