Summary: Unary minus on static const class variable triggering
linker error
Product: gcc
Version: 4.4.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: sander.l...@gmail.com

Example
The use of an unary minus on a static const variable in a class seems to
trigger a linker error (undefined reference to ...)
Workaround: if instead of the unary minus "-var", a binary operator "0.0-var"
is used, the bug disappears.
See attachment for example.
$ g++ -v
