Bug #: 55543
Summary: diamond shaped inheritance involving strings leads to
crashing executables (MinGW, 32 bit)
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: martin.giesek...@uos.de
Created attachment 28837
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28837
source file to reproduce the issue
When I compile the attached code with g++, mingw32 (gcc 4.7.2), I get an
executable that crashes with the following exception:
terminate called after throwing an instance of 'std::length_error'
what(): basic_string::_S_create
This only happens for mingw32. A 64 bit build of the same code works correctly.
So do all 32/64 bit builds for Linux targets I've tested.
Command line:
g++ --save-temps -v -m32 inherit.cpp
Message output:
