version: 12.9.0
gcc: 8.2

message:

What flags, if any, did you pass to ./configure? Does this happen when running Node.js, while building it, or only with specific scripts?

[phantom9999]

build script is here:

workspace=$(cd $(dirname $0) && pwd);
./configure --without-snapshot --prefix=$workspace/output
make -j8 && make install

then write a script(/tmp/ddd.js):

const a = {
    b: 2
};

console.log(a);

i run it with:

node /tmp/ddd.js

then it core dump with message:

#
# Fatal error in , line 0
# Check failed: (isolate_->embedded_blob()) != nullptr.
#
#
#
#FailureMessage Object: 0x7fff8e43f6e0 (core dumped)

the core stack is:

Program terminated with signal SIGILL, Illegal instruction.

it will not task a core dump when i use node v12.6, but it takes a core dump at v12.9

I can reproduce this on master, though ./configure --without-snapshot --without-node-snapshot works fine. Maybe we should just add an implication here.
