Hi,

I am getting this when trying to compile Rust 0.6 (tarball downloaded via the website):

I just deleted everything and compiled it again. Now it makes it to stage2, and then fails with the same error.

@clboussard

I can't compile to. I'm on debian squeeze.
The output is the same.

@crazymykl

It would probably help diagnosis if you followed the error's advice
note: try running with RUST_LOG=rustc=1,::rt::backtrace to get further details and report the results to github.com/mozilla/rust/issues, and posted that output.

More helpful would be running rustc under gdb and breaking on rust_task_fail. The backtrace from there is must more useful.

progval commented Apr 8, 2013

@crazymykl That's what I did. See the first line of the block.

@jdm How?

jdm commented Apr 8, 2013

Run make with VERBOSE=1 to see the actual command that's failing. Run gdb --args ... where ... is the command you just found, and use break rust_task_fail followed by run. When the breakpoint is hit, use bt and paste the output.

@progval mea culpa. At least some attention was drawn to the bug by my mistake.

What do you mean? I have cc in my PATH.

And stages 0 and 1 worked once. (I tried to run "make clean" and then "make", but stage 0 fails again)

I've updated the title to reflect the error your logs show. I'm mystified why run::program_output would report that cc can't be found if it's in your path; it just ends up using fork and execvp.

jdm commented Apr 9, 2013

Although, reading the source of rust_run_program.cpp, apparently the fork call is failing.

progval commented Apr 9, 2013

Could that be because it cannot allocate enough memory to the fork? The process uses about 35% of my RAM when it crashes (I have no SWAP).

EDIT: That would explain why stages 0 and 1 worked once.

I closed Firefox (ie. what consumes the more memory ;) ) and stage0
just passed.

progval commented Apr 9, 2013

and... it worked!

I'm not closing this issue as requiring so much memory (more than 2GB) is still a problem, isn't it?

Alas, rustc does use a lot of memory. I think there's no other bug here; reopen if I'm confused.
