Ok, the next step is to compile your app without -g. The reason is because hash tables are used in the dwarf debug generation, and I want to see if that one is the problem or other uses.

Tested with flags : -m64 -w -debug -unittest (removing the -gc flag I usually
use).

I « successfully » triggered the error as well.

I've tried various schemes to induce it to fail, and done a code review. I can't find anything wrong. I need a test case.

Sorry for being unavailable the past few days, I was moving from France to USA.

I can trigger the error on a regular basis with the following codebase :

git clone git://github.com/deadalnix/SDC.git
cd SDC
git checkout aa_assert
make

the program is made to be compiled on linux. My computer is a dual core athlon with 4Gb of RAM.

I can't come up with a simple test case that trigger the error, because it seems that size matter here.

When I try your instructions, I get:

which is not the error you reported.

Running into this issue since today. I'm developing on a 64 bit windows machine targeting 32 bit, production machine is running 64 bit debian. Using DMD 2.062 on both boxes.

The bug pops up at the strangest moments. I can confirm it's indeterministic, but so far the production box never failed to build. That said, I don't build very often on production, esp. if the build failed on the dev box ;). For the sake of completeness I've just tried compiling a version of the project on the production box which almost always fails on the dev box. So far it keeps succeeding.

On the windows box I recently flipped the LARGE_ADDRESS_AWARE bit on dmd.exe to work around issue 6498, perhaps this has something to do with it?

As an indication of project size, the project is medium sized: vibe.d + 1937 lines, but it's very CTFE heavy: we're using vibe.d's diet template parser to generate 21 rather large web pages. Compilation requires a little over two GB of memory.

Is there any additional info I can provide?

I think somebody should provide a (snapshot of) project to compile to investigate the problem, deadalnix's link is outdated and guessing based on valgrind output is not a very good idea.

Yeah I was afraid of that :)

I'd have to take it up with the PHB's, not sure what the answer will be. TBH I doubt I can make the code public. Not that there's anything of value in it, but you know how it is...

I'll report back when I've got an answer.
