New issue 3174 by [email protected]: CHECK(this_entry->maps_->size() > 0)
failed, hydrogen-check-elimination.cc, line 283
http://code.google.com/p/v8/issues/detail?id=3174
A couple of instances of the above CHECK failure have been seen on the
Linux Debug GPU bot running the Maps test. This test runs a significant
amount of the JavaScript from the new maps.google.com, so it represents a
real-world use case.
The failing builds:
http://build.chromium.org/p/chromium.gpu/builders/Linux%20Debug%20%28NVIDIA%29/builds/25247
http://build.chromium.org/p/chromium.gpu/builders/Linux%20Debug%20%28NVIDIA%29/builds/25216
Log excerpt (because the logs expire):
#
# Fatal error in ../../v8/src/hydrogen-check-elimination.cc, line 283
# CHECK(this_entry->maps_->size() > 0) failed

Unfortunately this error is very intermittent. The first time it showed up
in the build logs there was no obvious cause, and coming up with a
regression range will be difficult or impossible. Hopefully it's possible
to reproduce with a sufficient number of runs of the test.
If you need any help running the test please email me directly. It requires
building Chrome in debug mode and running:
src/content/test/gpu/run_gpu_test.py maps --show-stdout
It's possible that more arguments might be required. Here's the full
command line from the bot:
/usr/bin/python
/b/build/slave/Linux_Debug__NVIDIA_/build/src/content/test/gpu/run_gpu_test.py
maps --show-stdout --output-format=gtest --browser=debug -v
--build-revision 252510 --test-machine-name "Linux Debug (NVIDIA)"
--gtest_output=xml:/b/build/slave/Linux_Debug__NVIDIA_/build/gtest-results/maps_pixel_test/maps_pixel_test.xml
