pstree

Err, based on that pstree, it looks like you had MAKEOPTS=-j7. The child of emake is "make -j7".

The tinderbox has this set - works for nearly all packages except few ones, ncurses are among them :


MAKEOPTS="-j 1"
NINJAFLAGS="-j 1"
EGO_BUILD_FLAGS="-p 1"
GOMAXPROCS="1"
GO19CONCURRENTCOMPILATION=0
RUSTFLAGS="-C codegen-units=1"
RUST_TEST_THREADS=1
RUST_TEST_TASKS=1

Please attach your build log that corresponds to the process tree you provided.

Also, I still really think this is a config issue on your end. emake is clearly passing -j7 to make; I don't see anything in the ebuild that would override MAKEOPTS.

BTW have a look at bug 646092 - similar issue there

Maybe something like this is needed? :

Rust uses a completely custom build system.

ncurses uses pretty normal looking makefiles along with autoconf.

That's why this bug makes no sense to me -- there's no obvious build system that needs fixing here.

I did some experiments to try and reproduce the problem myself, and was unable to get anything resembling your pstree with anything other than MAKEOPTS=-j7.

OMG - needed hours here to realize that this is indeed PEBKAC.

Sry.
