NodeJS get Floating point exception

[Julius1985]

Node.js Version: v4.4.7
OS: SUSE Linux Enterprise Server 10 SP3 (x86_64)
Scope: Install

Hi, I have a little problem, I installed nodejs into a SUSE Linux Enterprise Server 10 SP3 (x86_64), but when I execute node -v command or another. I get "Floating point exception". Any idea whats going on?

Can you run grep -i flags /proc/cpuinfo and post the output here? Also: gdb node, then run -v, wait for the crash (assuming it happens) and then run bt and disassemble $rip-40,$rip+40 in gdb and share that output, too?

(like this:)

$ gdb node
[blah blah free software blah]
(gdb) run -v
Starting program: /usr/bin/node -v

gdb node, then run -v,

The output of disassemble $rip-40,$rip+40 in gdb would still be kinda interesting (maybe the paste got cut off there).

Also, that’s an odd place for an error – does running env | grep -i ^LD_ in the shell yield anything for you?

env | grep -i ^LD_, doesn't produce nothing for me

What’s your glibc version, if you can look that up somehow? Is it up to date? The copy of the glibc sources that I’m looking at don’t seem to correspond 100 % to the disassembly here…

Yeah, I’m pretty sure it’s a glibc bug that has been fixed in glibc >= 2.5. And unfortunately, it’s nothing that Node can do anything about. :/

Ok, thanks for your help. I'll upgrade my SO version El 6/3/2017 6:44 p. m., "Anna Henningsen" <notifications@github.com> escribió:
