[ruby-core:21711] Re: [Bug #744] memory leak in callcc?

Michal,

I finally managed to get a working Ruby 1.8.7 on ppc64 with and without
MBARI patches
under OSx 10.5 as follows:

export ARCH_FLAG="-arch ppc64"
CFLAGS="-O2 -g -m64 -fno-stack-protector"  configure

There may yet be a problem with my build configuration, but I don't think
the MBARI patches have anything to do with these failures.
Both patched and unpatched versions fail the same 6 tests.
Does anyone have a ppc64 (64-bit code) Ruby that does not fail these tests?

Note that I am using the PowerPC patch of 1/23/09.  For now, it must be
applied manually
after the MBARI7 patch.  I will integrate it after it has been tested on
x86_64.
(It should be called the 64-bit patch, as it is intended to fix x86_64 as
well as ppc64)

The PPC patch changes the meaning of the STACK_WIPE_SITES #define.
See rubysig.h for details.

One interesting observation is that my *unpatched* ppc64 ruby did not leak
when executing:

ruby -e "loop{@x=callcc{|c|c}}"

This could be because the ppc versions put ruby call arguments on the heap
rather than the 'C' stack.

results:

The patched ppc64 Ruby runs the test suite about 30 seconds quicker.
341 vs. 312 seconds
It used a bit less RAM, but the difference wasn't large:
114Mb vs. 106Mb peak VSIZE

I've included the details of the run below.
Can anyone verify whether or not these failures occur with unpatched
1.8.7-p72?
