<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>While compiling the new release (6.8.1, with both the primary
source and the extra libraries) I experienced a gcc error, gcc of course called
by ghc. I’m compiling 6.8.1 with ghc 6.6.1. The gcc version
is 4.1.1.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve seen similar behavior in the past where some sort
of heap corruption occurs within gcc and triggers an internal compiler
error. So this may not be a true ghc error at all, but one can’t
completely rule it out.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This type of error, especially appearing at random, is
suggestive of a memory hardware problem. To eliminate this possibility I
ran memtest86 for several hours on the machine. No errors were detected.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ll repeat the build again from a fresh directory to
see if the problem is repeatable. Then I plan to run a build after
upgrading gcc from 4.1.1 to 4.2.1. I’ll report the results.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The environment is Linux using kernel 2.6.21.<o:p></o:p></p>
