Description David Schmitt 2012-11-15 05:22:56 UTC
When running nuget 2.1.31022.9038 on mono-3.0.1 I sometimes get random segfaults. Seemingly from some kind of data corruption, as sometimes it doesn't segfault, but produces ArgumentNullExceptions:

WARNING: Argument cannot be null.
Parameter name: name
Successfully installed '....'.
Successfully installed '....'.
Successfully installed '....'.
Successfully installed '....'.
Unable to find version '....' of package '....'.

In a normal run all packages are installed without error. I cannot reproduce this on MS.NET. I can reproduce crashes on current mono 2.10.

I've attached several collected stacktraces.

packages.config that is used when having segfaults

For testing I'm running the following loop, which terminates with a crash, usually within ten iterations:

while mono --debug --runtime=v4.0.30319 ./nuget.exe install ./packages.config -o ./packages; do echo; rm -Rf packages; done

Using sgen seems to lead to a deadlock:

D'oh, it helps telling gdb about the correct binary to use.

I get this on all runs:
Unable to find version '' of package 'Arebis.CodeGenerator'.
Comment 6 Rodrigo Kumpera 2017-07-14 23:26:47 UTC
Nuget works with latest mono.
