[Octave-bug-tracker] [bug #51530] fsanitize=undefined errors

[Dmitri A. Sergatskov]

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
