<p>Hi Simon, <o:p></o:p></p>
<p>Thomie changed it so the in place gcc can be called from the testsuite. The tests should pass now.
<o:p></o:p></p>
<p>Kind regards, <br>

past. Particularly when compiling shared libraries for tests since GHC wants to link in the RTS, which makes the files considerably larger and harder to debug so<o:p></o:p></span></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span lang="EN-US">It means (with shared libraries) that I’ll end up with multiple RTSs loaded (at least in memory, which means stepping in gdb I have to keep track of the memory
