Summary: Template-Methode in Shared Object not resolved when
compiled with -O2
Product: gcc
Version: 4.3.4
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: r.men...@nice2cu.de
Compiling the application with -O2 crashes the application because of a
symbol-not-defined-error, while compiling without -O2 Option or using -g
works.
Actually I am overloading and not specializing an template-methode, which is
propabily not the right way, but the example is trivial and because the
application crashes when compiled with -O2 and not when compiled with -g or
without the -O2 option i decided to send this bugreport.
