Hi, I have a Pharo image that crashes the VM on startup. The crash report below seems to incriminate GC. Should I make it available somewhere online? What's most convenient?

Don't care. Anywhere it can be downloaded from. Also, try running with -leakcheck 15, preferably in an assert VM and see if that gets you additional information.

Right. This VM is prior to the bug fixes in VMMaker.oscog-eem.2320:
Spur: Fix a bad bug in SpurPlnningCompactor. unmarkObjectsFromFirstFreeObject, used when the compactor requires more than one pass due to insufficient savedFirstFieldsSpace, expects the corpse of a moved object to be unmarked, but copyAndUnmarkObject:to:bytes:firstField: only unmarked the target. Unmarking the corpse before the copy unmarks both. This fixes a crash with ReleaseBuilder class>>saveAsNewRelease when non-use of cacheDuring: creates lots of files, enough to push the system into the multi-pass regime.
Pharo urgently needs to upgrade the VM to one more up to date than 2017 08 27 (in fact more up-to-date than opensmalltalk/vm commit 0fe1e1ea108e53501a0e728736048062c83a66ce, Fri Jan 19 13:17:57 2018 -0800). The bug that VMMaker.oscog-eem.2320 fixes can result in image corruption in large images, and can occur (as it has here) at start-up, causing one's work to be irretrievably lost.

I'm not sure where to get or how to build an assert VM.
When you build a phar. VM under build.macos64x64/pharo.cog.spur using the mvm script (mvm -A) you produce an assert VM in PharoAssert.app.
Note that if you build an Assert VM you will be able to manually patch the image in lldb so that you can rescue it. It looks like this:
$ *lldb PharoAssert.app/Contents/MacOS/Pharo*
(lldb) target create "/Users/eliot/oscogvm/build.macos64x64/pharo.cog.spur/PharoAssert.app/Contents/MacOS/Pharo" Current executable set to '/Users/eliot/oscogvm/build.macos64x64/pharo.cog.spur/PharoAssert.app/Contents/MacOS/Pharo' (x86_64). (lldb) settings set -- target.run-args "clap_broken.d9e5daa.image" (lldb) *b warning* Breakpoint 1: 3 locations.

Most, if not all, the VMs between 1 Jan and 15 Mar have bugs that are triggered either by the automated test suite or the bootstrap process.
The blocks I can see at the moment are:
- Multiple builds have failed with an internal compiler error on the sista builds. -- The earliest occurrence I could find was commit 1f0a7da, but it may have been earlier. - Even if the Mac builds show success in travis, they aren't making it on to files.pharo.org. -- I haven't ever worked with this code.
Not directly related, but: - Bintray hasn't been updated since 8 March 2018.
I think it could also be useful for files.pharo.org to have release candidate links available, which would help people to focus testing on a particular VM. They would need to be manually maintained, but I think the benefits would be worthwhile.

I didn't mean that we would always be looking to release a new version, but there have been multiple occassions in the past when you've asked people to try a particular VM to see if it solves a problem. In those instances, marking it as RC would make it simpler for others to contribute to the testing and give you more confidence to promote it to stable.
Actually, if the link existed all the time, but most of the time it was the same as the stable version, I'd probably just use it as my download link, which would mean that I'm testing the RC whenever it comes out, and stay with it while it is stable and there isn't a new RC.

Hi,
I seem to be getting more of these errors recently. I'm on Mac Mojave 10.14.5, Pharo-7.0.3 64 bit, with the current stable vm (Mac OS X built on Jan 5 2019 19:11:02 ).
Running the leak checker returns some leaks:

The when using `storePointerUncheckedofObjectwithValue` I seem to get an error:

Is this a problem with the way I compiled the assert vm? And is there a way to explore how the leaked objects get created?

I'm not sure where to get or how to build an assert VM.
When you build a phar. VM under build.macos64x64/pharo.cog.spur using the mvm script (mvm -A) you produce an assert VM in PharoAssert.app.
Note that if you build an Assert VM you will be able to manually patch the image in lldb so that you can rescue it. It looks like this:
