#936: SIGABRT in VRT_synth_page
 Reporter:  kwy    |        Type:  defect  
   Status:  new    |    Priority:  normal  
Milestone:         |   Component:  varnishd
  Version:  trunk  |    Severity:  normal  
 Keywords:         |  

 the following vcl, possumly erroneous, compiles:

 sub vcl_recv {

    synthetic "HELLOO";
    return (error);

 and given a request, fails with SIGABRT.

 If I were to guess, it is likely due to the synthetic in vcl_recv having
 no object to attach itself to. But I am just guessing. Backtrace
 follows;this is reproducable on demand.

 0x00007f32d43c9f93 in poll () from /lib/libc.so.6
 (gdb) c
