[Steve Fink [:sfink] [:s:]]

I'm not sure what's going on here, especially with it being a rare intermittent. I wanted to guess is that it happens when it's doing an incremental build, except that one of the failures is on try.

It's displaying the error message just after it enters the gtest directory, which is the (incorrect) directory that used to hold the libxul.so-gdb.py file. (Hm... does that directory need it too? Are there gtest binaries that want the prettyprinters as well?) Unless the make output is getting mixed up, that really seems like it is running off of a stale moz.build configuration?

[Mike Hommey [:glandium]]

Attachment: Bug 1646306 - Avoid trying to install libxul.so-gdb.py from two places.

The Libxul template was invoked from toolkit/library/build and
toolkit/library/gtest, which means there was a possibility that two
makes would simultaneously try to create libxul.so-gdb.py because it was
being installed twice to the same place.
