Hi,

I look after a few applications that crash from time to time. Usually I can use the ex.err to track down the fault in the source code. Occassionally the crash message is "A machine level exception occurred during execution of this statement". These ones leave me a little nonplussed. The crashes occur infrequently and across a large range of different machines. Whenever I ask the user for more information I get the conversational equilvalent of a shrug. The users are half way across the country from me, and so I can't watch it happen and the user can't reproduce it.

Can anyone offer me some help on how to diagnose faults like this one

• C:\EUPHORIA\include\machine.e:296 in function allocate_string()
  A machine-level exception occurred during execution of this statement
  s = {}
  mem = <no value>
  

• ... called from .\Common\Private\dlla2.e:121 in function dllFunc()
  nama = {71'G',101'e',116't',80'P',114'r',105'i',118'v',97'a',116't',101'e',
  80'P',114'r',111'o',102'f',105'i',108'l',101'e',83'S',116't',114'r',105'i',
  110'n',103'g',65'A'}
  par = {
  9702016,
  9702016,
  {},
  {32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',
  32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',
  32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',
  32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',32' ',
  <snip>
  

or this one

• C:\EUPHORIA\Private/eucom.ew:1626 in function quick_activate()
  A machine-level exception occurred during execution of this statement
  obj_ix = 1
  fore_color = 0

  pcontrol = <no value>
  mset = 8733316
  ok = <no value>
  ppvIFont = 1623196
  riid = 9406540
  ppvClient = <no value>
  ppvAdvise = <no value>

P.S. I'm sorry if my use of forum tags is all wrong. I tried a large number of combinations before settling on this look.
