Incompatibility with gcc 4.3.0 ?

Hello,

I've upgraded my laptop from Fedora8 to Fedora9, and I encounter huge difficulties trying to install smartEiffel 2.3. I suspect the new version of gcc to be responsible of this, as all was working fine before.

Does someone succeeded in compiling smartEiffel 2.3 with gcc 4.3.0?

Hi,

I haven't tried that version yet. Maybe it's an older issue, Valery
Croizier reported issues with gcc 4.2.1 (under windows).

I had a quick look at http://gcc.gnu.org/gcc-4.3/changes.html (general,
c-related and ia32-related changes). Nothing set off an alarm bell in my
head.

Running our test suite with those gcc releases will help isolating 
problems. Before, we need to fix some problems with the current svn 
compiler.

gcc 4.3.0 has optimisation problems at -O2 level.
Smarteiffel will compile correctly at -O1 level.

Hello,

Just to confirm what you've said, I patch the system.se file to change in [boost] section -Os to -O1, and it now compiles fine.

Thank you for the information.
