While trying to implement setcond on TCG ARM, I have discovered it does not work anymore. I have bisected this regression to:
commit 6113d6d3169393c323ac4c82d756a850145a5e7a Author: Paolo Bonzini <pbonz...@redhat.com> Date: Fri Jan 15 09:42:09 2010 +0100 change while to if The while loop will be executed exactly 0 or 1 times, depending on env->exit_request. Signed-off-by: Paolo Bonzini <pbonz...@redhat.com> Signed-off-by: Anthony Liguori <aligu...@us.ibm.com> The assertion is actually triggered. When the next patch removing the assertion is also applied it segfaults instead. The patch does not seem to be wrong. Moreover I have tried to debug the problem, but I failed to as it looks like an Heisenbug. Compiling this file with -O0 also fixes the problem. Does someone have an idea? -- Aurelien Jarno GPG: 1024D/F1BCDB73 aurel...@aurel32.net http://www.aurel32.net
