Run hhvm as user

[bytestostring]

Hi.

I tried to run hhvm fastcgi server as user.
Command line (run as root):
hhvm --mode server -vServer.Type=fastcgi -vServer.Port=9000 --user admin
Output:

mapping self...
mapping self took 0'00" (115530 us) wall time
loading static content...
loading static content took 0'00" (1 us) wall time
Core dumped: Segmentation fault
Stack trace in /tmp/stacktrace.2665.log
Segmentation fault

I checked /tmp/stacktrace.2665.log, but it's empty.

How I can run hhvm as user (from root bash-session) ?

I can't find documentation by "-vServer.Type, -vServer.Port" options besides this link: (https://github.com/facebook/hhvm/wiki/FastCGI). In man hhvm they are not mentioned.

I checked /tmp/stacktrace.2665.log, but it's empty.

This is a consequence of a packaging problem which we are in the process of resolving (but it looks like it could be a few months). Can you run this command under gdb and get a backtrace from it that way?

Okay, gdb, first time:

(gdb) file /opt/hhvm/bin/hhvm

(gdb) run --mode server -vServer.Type=fastcgi -vServer.Port=9000 --user admin

I have installed jemalloc 3.5.1 by instruction.
I checked directory /usr/local/include/jemalloc, there is one file "jemalloc.h".
I downloaded jemalloc 3.5.1 again, unpacked it, and moved all files (except jemalloc.h) from /tmp/jemalloc-current/include/jemalloc to /usr/local/include/jemalloc. And run gdb again.

Output gdb:

(gdb) r --mode server -vServer.Type=fastcgi -vServer.Port=9000 --user admin

Thank you.

After hhvm crashes in gdb can you run bt at the prompt to generate a backtrace?

Is this still an issue?
