Crash in camel on PowerPC, gcc regression

Bug Description

The camel library crashes on powerpc due to a gcc regression. The culprit is some optimized code in camel-search-private.c.

The actual bug is in gcc, but this needs to be fixed for dapper. I am attaching a patch that disables the optimizations on powerpc to avoid the crash.

Temporary patch. Please remove post dapper release so that the actual bug in gcc can be fixed.

     - thanks Ben Collins for providing the fix. evolution-data-server crashed
       on PowerPC on filtering specific mails. This was due to optimizations
       and are likely to be a GCC problem. To get on with life, we add this as
       a temporary fix and will hopefully a fixed GCC in Edgy. (Malone: #44061)

Ben, Matthias: what do you think about the following upstream comment?

Comment #7 from Jeffrey Stedfast 2006-05-10 19:11 UTC

is it really necessary to comment out the register keyword? since register is
used quite a lot in camel, I think the problem is related to inline, no?

I wonder if a better fix would be to #define inline to nothing in config.h or
something if the system is ppc.

that would penalize all files; are the variables really placed memory
locations without the register keyword?
