             Bug #: 55109
           Summary: internal compiler error: Segmentation fault while
                    reporting error in template function instantiation
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ZetaetaDaniel@gmail.com


The compiler command was:

g++ -DHAVE_CONFIG_H -I.    -O0 -g -std=c++11  -I src/ -Wall -Wextra -Werror
-Wno-error=unused-variable -Wno-error=unused-parameter
-Wno-error=unused-but-set-variable  -MT mc___server-NetworkServer.o -MD -MP -MF
.deps/mc___server-NetworkServer.Tpo -c -o mc___server-NetworkServer.o `test -f
'src/network/NetworkServer.cpp' || echo './'`src/network/NetworkServer.cpp

The compiler output was (template stuff formatted for readability):

with preprocessed source if appropriate.

The backtrace of the segfault is:

which is of course very incomplete, and I am currently compiling gcc with debug
symbols to get a better backtrace, but it will take some time.
