Where are the exit codes? NaCl process exited with status -1073741674 (0xc0000096)

[Ed O'Loughlin]

Hi,

I'm trying to load a pexe and I'm seeing this in Chrome's stdout:

[3084:3704:0219/122241:ERROR:nacl_process_host.cc(289)] NaCl process exited with status -1073741674 (0xc0000096)

I've set NACL_EXE_STDOUT, NACL_EXE_STDERR and NACLLOG but only the file specified in $NACLLOG is created and it's empty, so this exit status is all I have to go on.

Is there a list of status codes somewhere? Google (the search engine) doesn't seem to know about them.

Thanks,
Ed. O'Loughlin

More to report. I tried it with only
  NACL_PLUGIN_DEBUG=1
  NACL_SRPC_DEBUG=255
  NACLVERBOSITY=255

and I now get a different exit code: 34304 (0x8600). My pexe initialises nacl_io for access to the HTML5 filesystem and I've got persistent quota in Javascript prior to loading the pexe.

There's a lot on stdout, but here's the last 79 lines. Note the "** abort() called" message, which is logged twice.

[Bennet Yee (余仕斌)]

the "** abort called" message is not being logged twice. what is happening is that the standard error output is intermixed with the log messages.  see the output for "pp:CompletionCallback..." and you'll similarly see two copies: one from the logging infrastructure to show the arguments of the syscall, and one from the execution of the write system call.

sorry, i don't know what code triggered the "** abort".
