Bug #: 55542
Summary: g++ segmentation fault
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: critical
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: hpsmo...@gmail.com

--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28833
Preprocessed code to reproduce the bug (gzipped)
The fault happened when instantiation a template member function.
If the template definition is moved before its use point, this bug doesn't
occur.
Preprocessed code is attached.
Command line and output:
$ LC_ALL=C g++ -v -std=gnu++11 -xc++ -c code.out
