[opensource-dev] TeamCity build production

[Aimee Trescothick]

OK, so I tracked down what's going on with the Mac builds, looks like we're tripping over an icky GCC 4.0 optimization bug which is "optimizing out" the NULL pointer checks in LLPipeline::compare_pools, probably inadvertently triggered by the changes for SNOW-643 (Water flickers and disappears in patches).

More info and a temporary work-around at SNOW-761

I'd appreciate it if someone more familiar with the work from SNOW-643 could take a look at what may be causing it and a better solution.

Aimee.

This has been fixed and exports since yesterday starting with build 207152 are producing correct bundles. One note: the name of the bundle is a bit confusing since it has "viewer-2-0" in it while the version is "2.1.0.xxxxx". This is because the internal hg branch I'm using is named that way. This will become "viewer-public" once we merge the export script there.
