Hmm, my bad, I fail to find a bug in genPrimitiveStringReplace

It appears that I messed up with git client... (bissecting on two different machines is not a good idea anyway)

What I find now is this:

- mac osx 64 squeak.cog.spur cog HEAD segv

- mac osx 64 squeak.cog.spur generated with VMMaker.oscog-cb.2274 and src/plugins/* from head is not OK (mangled)
- mac osx 64 squeak.cog.spur generated with VMMaker.oscog-cb.2274 and src/plugins/* taken from old commit is OK

  https://github.com/OpenSmalltalk/opensmalltalk-vm/commit/3010e4465405f6ec7a289fc3a3d21eb324816a8f#diff-2ecd46f56f9702ad7a50219dd086a8c5

So that's at least two different problems, one in the plugins, one in

The problem in generated plugins is in MiscPrimitivePlugin.c

There are not many changes, so I'll see if I can identify the problem and fix it in VMMaker.

So I have fixed the code of primitiveDecompressFromByteArray from MiscPrimitivePlugin

but IT'S NOT IN VMMaker... I fixed the Squeak trunk version (Graphics-nice.385), I presume there is a similar thing in Pharo.

We can't continue with this Misc thing, it's not manageable.

I've also pushed the fix on github.

Now remains the 64bits cog spur VM problem

Then there will be the problem of the 64bit cog spur vm...

Since I experienced mangled display when generating source with VMMaker.oscog-cb.2274,

I suspect that the problem is related to genPrimitiveStringReplace introduced in VMMaker.oscog-cb.2273

I can generate a working Win64 squeak cog spur VM at least up to VMMaker.oscog-cb.2272, no time to finish bissecting right now...

Hmm, I tried to fix declaration of unskew, but it does not seem enough...

Hi Clement,

I let a comment on line 1972 of src/plugins/BitBltPlugin/BitBltPlugin.c on commit
https://github.com/OpenSmalltalk/opensmalltalk-vm/commit/1dd1a9c0d61ed1c367fb226e59ce0386af3bf5ed

and another one in https://github.com/OpenSmalltalk/opensmalltalk-vm/commit/4ff34235c24ea2fd690287f96a73834e744ad6c9

The problem is that a local variable unskew was generated as unsigned int instead of int in BitBlt, but we then test if unskew < 0 which is obviously going to be eliminated as dead code...

I did not try to compile the VM, but I'm pretty sure this is related.

Hi,

The latest VM that I build from open-smalltalk VM 2278 or 2280 does not work (Stack overflow at start-up OR bugged UI with strange color making any text impossible to read). 

I have the problem on 2 different computers, Mac OS X and Linux.

I am able to build successfully the VM from 2274 but I can do it only with a previous version of the platform files (else I got a linking error - scavengeLog: used but not implemented).

I am not sure the problem comes from the recent platform files or the recent changes in the VMMaker packages since they need each other to be able to be compiled.

What is the right way to work around this problem ?

I am about to commit on VMMaker package Sista update but I cannot merge with 2280 since I can't compile a working VM from there, so I'll commit without merging if I cannot solve this problem

Thanks,
