Summary

0000630: bad location with tmp CIL variable

Description

Here is an example :

int tmpVarCilInCondMultiple(char c)
{
  if(ap_tolower(c) && ap_isspace(c))
    return 1;
  else return 0;
}

And the resulting transformed code :

int tmpVarCilInCondMultiple(char c__tmpVarCilInCondMultiple )
{
  int tmp__tmpVarCilInCondMultiple ;
  int tmp_0__tmpVarCilInCondMultiple ;

  tmp__tmpVarCilInCondMultiple = ap_tolower(c__tmpVarCilInCondMultiple);
  if (tmp__tmpVarCilInCondMultiple) {
    tmp_0__tmpVarCilInCondMultiple = ap_isspace(c__tmpVarCilInCondMultiple);
    if (tmp_0__tmpVarCilInCondMultiple) {/* ... */ }
    else {/* ... */ }
  }
  else {/* ... */ };
  /* ... */
}

where locations of the if statement was lost (locUnknown), because of the
This is very embarassing for PathCrawler.

~0001340 monate (reporter) 2010-12-21 10:04	I cannot reproduce your issue: could you check that the bug is still there? Using frama-gui, I can see that the if statements are properly located on line 3.

~0001364 monate (reporter) 2011-01-04 18:59	fixed in SVN 11167 and probably since 11080.
