Summary: lto1: internal compiler error: in lto_wpa_write_files,
at lto/lto.c:1518
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: vincenzo.innoce...@cern.ch
I'm having several shared library links failing with this error when compiling
with -flto -fuse-linker-plugin
see below.
At the moment the librabry giving problems are complex and I've not yet manage
to reproduce the error with a simple test-case.
Could you suggest anything I can do to provide you with just few
(intermidiate?) files to reproduce the problem just at "lto1" level?
