Regression: CondaMemoryError when building about conda-build HOT 7 CLOSED

@mxschmitt what about with conda-build=24.3.0 and py-lief<0.14?

from conda-build.

Fixed in #5348, to be included in the upcoming patch release conda-build 24.5.1

from conda-build.

I can confirm that:

good: py-lief=0.12.3
bad: py-lief=0.14.1

Note: There is no 0.13 on conda.

Quite a large range: lief-project/LIEF@0.12.1...0.14.1

from conda-build.

I got a minimal repro:

curl -O https://nodejs.org/dist/v20.12.0/node-v20.12.0-linux-arm64.tar.xz
tar -xf node-v20.12.0-linux-arm64.tar.xz

python -c 'import lief; binary = lief.parse("node-v20.12.0-linux-arm64/bin/node"); print(str(binary))'

Expected: Some stringified value
Actual: MemoryError: std::bad_alloc

good: py-lief=0.12.3
bad: py-lief=0.14.1

Maybe we should re-think the str() in get_uniqueness_key which was added in #5228 - with the good py-lief version it ended up in a 33 MB long string which does not sound ideal.

Should I file it upstream that it now ends up in MemoryError: std::bad_alloc?

from conda-build.

Update: lief-project/LIEF#1039 (comment)

from conda-build.

Oh, my bad! The change from gh-5228 to use str(file) is simply wrong; we should just return the filename instead (this is what the previous binary.name did).
Thanks for the bug report!
I'll put a fix together in a bit.
