Description

[Jason Orendorff [:jorendorff]]

Sometimes jsreftests time out on Android, with the following symptoms:

• Android 4.3.

• The number of reports is small.

• The test being blamed actually passed, as indicated by REFTEST INFO | Result summary: with nothing Unexpected and REFTEST SUITE-END | Shutdown in the log.

• Subsequent output is like this:

  In particular,

• Long pause after the three WARNING lines.

• TEST-UNEXPECTED-FAIL | ... | application timed out after ... seconds with no output appears in the log

• Crash at [@ libc.so + 0x1c3dc].

I don't think it is a bug in the test suite or the JS engine. The test passes or is skipped.
