Since landing <http://trac.webkit.org/changeset/89136> (bug #62767), the unit test step on the GTK Linux {32,64}-bit Debug bots have been failing: For r89136: http://build.webkit.org/builders/GTK%20Linux%2032-bit%20Debug/builds/15898/steps/run-api-tests/logs/stdio For r89138: http://build.webkit.org/builders/GTK%20Linux%2032-bit%20Debug/builds/15898/steps/run-api-tests/logs/stdio http://build.webkit.org/builders/GTK%20Linux%2064-bit%20Debug/builds/23470/steps/run-api-tests/logs/stdio It's not obvious to me that either <http://trac.webkit.org/changeset/89136> or <http://trac.webkit.org/changeset/89138> relates to this failure. Notice, build-api-tests (which is called by run-api-tests) only pertains to the Apple Mac/Windows port and will die() with "TestWebKitAPI is not supported on this platform.\n". So, I would have expected this step to always fail on the GTK bots. Also, this "unit test" step only appears since r89136 (weird).
This issue also affects the Snow Leopard Debug bot: <http://build.webkit.org/builders/SnowLeopard%20Intel%20Debug%20%28Tests%29/builds/713> See comment 12 of 62767 and bug #62918 for more details.
