Confirmed on r173122 of trunk, using the command-line args provided by the
reporter.
I have managed to traced it back to happening somewhere between r172185 (works)
and r172316 (ICEs) of trunk. Looking through the Changelogs for "reload", the
most likely candidates are:

someone else will be able to work out which change it was.

This appears to be fixed on trunk . It appears to work with the command line
options that are specified on 4.6 branch.
Reclassified.
