 Bug #: 53407
   Summary: ICE compiling pcre-8.21 in
function_and_variable_visibility, at ipa.c:1002
Classification: Unclassified
   Product: gcc
   Version: unknown
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: lto
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: rainer-gccb...@7val.com


g++ throws an ICE when linking pcre-8.21 with -flto, it works with -O3. Since
the bug is in the linker phase, I don't have any preprocessed files I could
attach. The pcre source code is available at
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/ If required, I can
supply the entire source directory, including the object files used in the link
line below, or any subset thereof.

The GCC used is the default Version included in Ubuntu 12.04 x86_64.

It turns out a single source file is sufficient to trigger the ICE:

Compile:
