Bug #: 55206
Summary: GCC Reports Ambiguity; clang and comeau disagree
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: d...@boostpro.com
I apologize for not doing the hunt to figure out what the standard says on this
one, but since GCC is the outlier I'm reporting it here. The error is:
g++ -I ~/src/boost/svn/release -Wall -Wextra -pedantic -Wno-long-long
-Wno-unused-parameter -Wno-unused -Wno-parentheses -D_GLIBCXX_DEBUG -g -O0
