>Description:

I tried this on amd64, sparc64 and big endian ARM, all on the same internet
connection. It reliably works on amd64, and 100% reliably fails on the big
endian machines:

> hg clone https://hg.mozilla.org/mozilla-central/ firefox

I tried playing a bit with python -m pdb, but it is too awkward for a C/C++
guy like me, so someone else please have a look at this.

Otherwise I'd need strong guidance for a full debug session ;-)
