New issue 2704 by [email protected]: cctest crashed on armv6
http://code.google.com/p/v8/issues/detail?id=2704
I got a crash on android devices while running cctest. Here is what I do:
1. compile the v8 code (v3.19.0, v3.18.5, v3.17.12) with command: make
android_arm.release -j9 armv7=false
2. push cctest to android phone
3. run cctest with command: ./cctest test-hasing, then I got a crash report.
Here is what cctest print:
#
# Fatal error in ../test/cctest/test-hashing.cc, line 184
# CHECK(runtime_hash == codegen_hash) failed
#
[1] Bus error ./cctest test-hashing
