New issue 4272 by [email protected]: SIGILL when running Emscripten
compiled script with --always_opt --nodead_code_elimination --always_osr
https://code.google.com/p/v8/issues/detail?id=4272
A script I compiled with Emscripten, will result in V8 terminating because
of a SIGILL.
It happens with only with the x64.{release,debug} version. And only when
running it with "--always_opt --nodead_code_elimination --always_osr".
It works with --turbo, so its properly an issue in CrankShaft.
The script has been attached (along with a smaller version where the same
thing happens).
I've tried to get a smaller script with the same issue, but if I remove any
significant chunk from the smaller version, the error disappears.
Here is what is printed in the terminal:
-------------------------
#
# Fatal error in .././src/objects-inl.h, line 4652
# Check failed: offset <= (1 << kSafepointTableOffsetBitCount).
