Follow-up Comment #1, bug #51530 (project octave):
My "verbatim"s got messed up.
Trying again:
HG ID for this build is "cda0614beaec"
configure --disable-docs --without-qt --without-fltk CFLAGS="-O0
-fsanitize=undefined" CXXFLAGS="-O0 -fsanitize=undefined"
running "make check" results in two runtime errors:
<...>
gcc_ubsan/liboctave/util/oct-inttypes.cc-tst
................../liboctave/util/oct-inttypes.cc:431:40: runtime error:
negation of -9223372036854775808 cannot be represented in type 'long int';
cast to an unsigned type to negate this value to itself
PASS 28/28
<...>
Fixed test scripts:
bc-overloads.tst ............................................ PASS
451/451
conv.tst .................................................... PASS
405/405
sparse.tst
..................................................../libinterp/corefcn/ls-mat5.cc:492:11:
runtime error: load of misaligned address 0x7f86637b5257 for type 'const
int16_t', which requires 2 byte alignment
0x7f86637b5257: note: pointer points here
68 2e 68 00 00 01 00 00 00 00 00 00 00 6c 6f 61 64 3a 20 65 72 72 6f 72 20
70 72 6f 62 69 6e 67
^
PASS 1204/1204
<...>
Dmitri.
