[Benjamin Poulain]

The test fast/js/stack-trace.html fails after this patch: http://build.webkit.org/results/Apple%20MountainLion%20Release%20WK2%20(Tests)/r148720%20(8143)/results.html

It needs rebaseline I guess.

This is happening on Lion as well:

Now the result is the same on each ports.  Do you think we should update the generic expected file? or It's wrong result.

For example:

http://build.webkit.org/results/EFL%20Linux%2064-bit%20Release/r148738%20(11789)/fast/js/stack-trace-pretty-diff.html

http://build.webkit.org/results/GTK%20Linux%2064-bit%20Debug%20WK1/r148739%20(1348)/fast/js/stack-trace-pretty-diff.html

http://build.webkit.sed.hu/results/x86-64%20Linux%20Qt%20Release/r148740%20(50291)/fast/js/stack-trace-pretty-diff.html

Yeah, update the generic file.  Clearly my build (i have a custom clang so i can have as an) is producing a different stack size so running out of stack space earlier.

We should probably work out how to make the test resilient to that in the future, but for now just update the text results.
