Changes (by olly):

  * milestone:  1.1.5 => 1.0.19


Comment:

 I've committed the patch to trunk (with an expanded comment pointing to
 the GCC bug and this ticket to help out future developers) as r14068.

 Since packages of 1.0.18 built successfully on Ubuntu hardy, it seems this
 bug doesn't affect 1.0 branch, though I wonder if it would be prudent to
 backport this to avoid any potential problems.  My initial thinking was
 that the bug must be in new code in chert (perhaps pack.h) but the log
 shows it failing topercent2 with the inmemory backend.  The only downside
 seems to be a likely performance degradation in the generated code.

 So setting the milestone to 1.0.19 for now.
