Having built node v4.2.2 I get a segmentation fault.

The binary shasum is: 6ec12774e7b80f3bc391ed0ebdc6890d9660907f v4.2.2/bin/node.

Because of this I recompile de binary using the command ./configure --prefix=<path> --gdb --debug in order to perform a backtrace.

Bellow the backtrace:

Does env OPENSSL_ia32cap=0 node app.js work?

@diegosanchez are you running this in some sort of virtualized environment like VirtualBox or something like this? Or is it running on a bare metal?

@bnoordhuis I think it is BMI2 that is absent, that causes this.

It is strange that OpenSSL did not pick up AVX+SSSE3, though

@indutny Not it isn't a virtualized env.

@diegosanchez so far it looks like OpenSSL assembly code is not supported by your CPU. To work it should either:

  • Have SHA support
  • XOP support
  • BMI2+AVX2+BMI1
  • Be an Intel CPU and have AVX+SSSE3

From the cpuinfo that you have posted - it looks like your CPU does not support either of this modes. (@bnoordhuis please correct me if I'm off with this statement).

The simplest fix would be to use ./configure --openssl-no-asm before building node.js. This will unfortunately make crypto slower, but it should work without crashing.

It seems that it env OPENSSL_ia32cap=0 node index.js works. I would like to know what that means (more research is needed).

So far, it is a good workaround.

I have narrowed down the issue a bit more here Project where I reproduce the error

@bnoordhuis

I would like to know what that means (more research is needed).

Here is documentation. In a nutshell, openssl tries (and apparently fails in your case) to auto-detect the CPU's capabilities. OPENSSL_ia32cap=0 tells it to skip auto-detection and just be very conservative.

@bnoordhuis @indutny awesome thanks.
Was useful for you to have a backtrace with this level of details? I'm asking because the default level of debug information is -g and I would like to update it to -g3 it it were useful.

Yes, it was helpful, thanks. The ud2 and the stack trace told me where to go looking.

Awesome! 👍 If you want to stick to LTS, the OpenSSL upgrade should be in v4.2.3 now too.
