I have a hard time finding the core dump (for some reason, apport doesn't
copy the core dump to /var/crash and in case apport is disabled no core
dump is made at all).
Anyway, I've built V8 with the arm.debug configuration (make arm.debug -j4
OUTDIR=./my-output-folder snapshot=off armv7=true armfloatabi=soft
armfpu=vfp) and get the following stack trace:
#
# Fatal error in ../src/cached-powers.cc, line 159
# CHECK(cached_power.binary_exponent <= max_exponent) failed
