Python error when running tests with libgmalloc - ValueError: invalid literal for long()

[Joseph Pecoraro]

* SUMMARY
Python error when running tests with libgmalloc - ValueError: invalid literal for long().

* STEPS TO REPRODUCE
1. shell> DYLD_INSERT_LIBRARIES=/usr/lib/libgmalloc.dylib ./Tools/Scripts/run-webkit-tests --debug
  => python error

* NOTES
Traceback (most recent call last):

ValueError: invalid literal for long() with base 10: 'GuardMalloc[sysctl-27646]: Allocations will be placed on 16 byte boundaries. GuardMalloc[sysctl-27646]:  - Some buffer overruns may not be noticed. GuardMalloc[sysctl-27646]:  - Applications using vec'


Looks like the run_command:

    return long(self._executive.run_command(["sysctl", "-n", "hw.memsize"]))

Gets the GuardMalloc output. Can that be ignored?

I don't know if this is worth fixing; the supported way to enable GuardMalloc is with --guard-malloc switch (-g in abbreviated form).
