702200 - Assertion in nanojit selftest with tr-float

Status: VERIFIED DUPLICATE of bug 679840

(Tamarin Graveyard :: Virtual Machine, defect)

Description

[Lars T Hansen]

tr-float 6825 + a local patch set for Vector.<float4>:

x86_64 Debug build MacOS 10.6, Xcode 3.2.6, SDK 105, gcc 4.0 (according to Xcode):

['test', 'nanojit', 'codealloc', 'allocfree']
Assertion failure: !byteLimit || byteLimit > blkSpaceFor(2) (/Users/lhansen/work/tr-float/platform/mac/avmshell/../../../nanojit/CodeAlloc.cpp:145)
Trace/BPT trap

Does not repeat in TR.

Comment 1

Hard to know where this comes from.  There's new code in nanojit/Allocator.h that handles alignment, but it's not obvious that any of the alignment special cases kick in during the selftest run.

Comment 2

[Lars T Hansen]

The reason this test does not fail in TR is that the test is not present in TR.

Comment 3

[Brent Baker]

Marking as a duplicate of bug #679840.

The reason that this failure is not seen in tamarin-redux is that the selftest was checked in but was never compiled, so it is not actually running. If you compile the selftest in tamarin-redux you will see the assert.
