Not able to create the new angular project because npm install returning segmentation fault(core dumped).

⠧ Installing packages...Segmentation fault (core dumped)
bnoordhuis commented 4 years ago

cc @nodejs/platform-aix (I know, it's not AIX but we don't have a PPC team.)

@narkhedek3 Would it be possible for you turn on core dumps (ulimit -c unlimited) and inspect the core dump with gdb afterwards?

gdb $(which node) <corefile> , then bt to get a stack trace and disassemble and info registers to get a disassembly of the segfaulting code.

Based on the output of a fairly recent Angular 'ng' issue (illustrative of the steps the ng tool is trying to take), it looks like your problem might be experienced with the 'npm' binary?

Can you see if your SIGSEGV is reproducible with something as simple as 'npm -v'?

miladfarca commented 4 years ago

Cannot reproduce the issue.

Compiled from source:

git clone https://github.com/nodejs/node.git
git checkout v12.18.3

Used binaries from the community:

wget https://nodejs.org/dist/v12.18.3/node-v12.18.3-linux-ppc64le.tar.gz

npm version is 6.14.6. Also tried 6.14.7 by upgrading with npm install -g npm@6.14.7

Environment on docker:

This isn't a Big endian machine correct?

Thank you for your responses, When I am using following tar file it is giving error https://nodejs.org/dist/latest-v12.x/node-v12.18.3-linux-ppc64le.tar.gz But after installing using following tar file issue is resolved https://nodejs.org/dist/latest-v12.x/node-v12.18.3.tar.gz

miladfarca commented 4 years ago

I also tried your first link within my Centos docker env and it's working fine.

Your second link is the src code, did you compile from src?

narkhedek3 commented 4 years ago

@miladfarca

Yes I have compiled src code

miladfarca commented 4 years ago

Could you please share your exact Centos version with cat /etc/*release. Having the core dump data will also help a lot: https://github.com/nodejs/help/issues/2900#issuecomment-671268522

There are no PPC docker images for Centos 7.7.1908 so I tried 7.6.1810 (as well as 7.8.2003) and they both work just fine. We will need your core dump data to look into the issue, you can upload it here and we can try analyzing it in our env or you can follow https://github.com/nodejs/help/issues/2900#issuecomment-671268522 and copy the data here.

You might have a specific libc (or another dependent library) installed locally which is causing our binaries to crash (and works fine when you compile it yourself).

Is gdb using the same node binary which caused the segfault? Assuming this: https://nodejs.org/dist/latest-v12.x/node-v12.18.3-linux-ppc64le.tar.gz

0x10649154 isn't part of uv__hrtime in your disassembled code. Also uv__hrtime is around the line 486 for me given the same node version:

(gdb) b uv__hrtime
(gdb) r
(gdb) bt
#0  uv__hrtime (type=UV_CLOCK_PRECISE) at ../deps/uv/src/unix/linux-core.c:486

Does running node --version work?

#1 0x0000000011275ad8 in uv__signal_handler (signum=17) at ../deps/uv/src/unix/signal.c:186

FTR, signum=17 is SIGCHLD. What seems to happen is this:

  1. Libuv receives a SIGCHLD signal (expected, okay)

  2. Libuv's signal handler tries to store the thread-local errno variable to avoid clobbering it

  3. glibc's errno PLT stub somehow jumps to address 0x0

This is the offending call (__errno_location() is a wrapper around errno):

   0x0000000011275ad4 <+68>:    bl      0x10564134 <0000082a.plt_call.__errno_location@@GLIBC_2.17>

And that jumps to:

#0  0x0000000000000000 in ?? ()

The PLT is a kind of dynamic jump table. My guess is that this is an async-signal-safety issue in glibc's dynamic linker, i.e., probably not our bug.

Maybe you can work around it by forcing ld.so to resolve all symbols eagerly:

$ env LD_BIND_NOW=1 ng new my-app

It's essential that ng passes on environment variables to child processes in order for that to work however.

@narkhedek3 - is this still outstanding??
