Bug ID: 71812
Summary: gcc6/c++/functional:1726:40: internal compiler error:
in assign_temp, at function.c:961
Product: gcc
Version: 6.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: noloader at gmail dot com
Target Milestone: ---
I'm working on OS X 10.8.5 with MacPorts 2.3.4 installed. I'm attempting to
compile Jack Lloyd's Botan (http://github.com/randombit/botan) with GCC 6.1
from the port. Botan is a C++ TLS library.
I don't have a minimal test case because I did not write the code. I'm hoping
one of the GCC devs with C++/STL knowledge can spot the issue. Or maybe spot
the bad interaction and craft a test case.
The MacPorts bug report is at https://trac.macports.org/ticket/51796. The
MacPorts maintainers suggested to file the bug upstream.
**********
I can't submit pubkey_pkcs8.ii.zip. It appears to be causing Gateway Timeouts.

Here's Botan's configuration. Also note the configuration uses -Wa,-q, which
means the Clang integrated assembler is used. I dont know if it makes a
difference, but its mentioned for completeness.
