crash on mipsel64 from v12.x #31118
Description
- Version: 12.14.0
- Platform: Linux localhost.localdomain 3.10.0 deps: update openssl to 1.0.1j #1 SMP PREEMPT Mon Sep 16 21:11:02 CST mips64 mips64 mips64 GNU/Linux
- Subsystem: gcc-4.9.3-3 gcc-7.3.0
I just build [email protected] on mips64el (loongson 3A3000) with --with-snapshot ，the result was successed. When I run nodejs, it crashed. The messages are as follows:
#
# Fatal error in ../deps/v8/src/execution/isolate.cc, line 232
# Embedded blob checksum verification failed. This indicates that the embedded blob has been modified since compilation time. A common cause is a debugging breakpoint set within builtin code.
#
#
#
#FailureMessage Object: 0xffffffacc0
Program received signal SIGTRAP, Trace/breakpoint trap.
v8::base::OS::Abort () at ../deps/v8/src/base/platform/platform-posix.cc:406
But [email protected] and [email protected] works fine. I found that when I build [email protected] with --without-snapshot，then nodejs works fine. Maybe mips64el has some problems with v8 snapshot.
The versions of v8 and nodejs are :
- [email protected] -> [email protected]
- [email protected] -> [email protected]
- [email protected] -> [email protected]
According to the nodejs building document, have to build nodejs with gcc>=6.3，but I build it with gcc 4.9.3-3 without errors. after crash,I use [email protected] to build nodejs,the result are same.
I also tried to build nodejs with crossing compiler [email protected] and [email protected], nodejs was crashed too.You can download them from
http://www.loongnix.org/index.php/Cross-compile , and direct download url [email protected] and [email protected] ,put the date directory to /usr/loca/
the crossing build script as follows(host: ubuntu 18.04 x86_64 and [email protected]):

Hi @bnoordhuis:
Thank you for help. Yes, mips(el) is not an officially supported
architecture, but less than nothing.
