Bug ID: 77770
Summary: Internal compiler error on source which compiles with
earlier versions.
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: zoltan at bendor dot com.au
Target Milestone: ---

The compiler command line
Source code which compiles with 4.7.2 (and I was told, but not tested, with
5.1.0 as well) fails with internal compiler error on 5.4.0 and 6.1.0.
It is a cross-compiler, in all cases generated with the following configure:
--target=arm-eabi --disable-libada --disable-libssp --disable-lto
--enable-languages=c
The host is GNU/Linux, cross binutils installed with --target=arm-eabi
It should be noted that it succeeds to compile the code for both ARM and THUMB
if optimising for speed and also for ARM optimising for size, but fails with
the THUMB and optimising for size case (the target architecture is ARM7TDMI).
Attached are the command line, the error message and the preprocessed source
file. This particular set of files was generated by the 5.4.0 compiler.
