Hi
I am seeing an ICE while compiling gcc for i586 from linaro 4.5 branch This ICE happens in libstd++ when compiling with -march=pentium -Os
If -march=pentium is not used then it compiles file and also -O2 works ok
ios_init.c: In destructor 'std::ios_base::Init::~Init()': ios_init.c:15899:3: internal compiler error: in dwarf2out_begin_epilogue, at dwarf2out.c:2859 Please submit a full bug report, with preprocessed source if appropriate. See http://gcc.gnu.org/bugs.html for instructions.
Is the error I get and if I revert r99474 the ICE goes away
here is command to reproduce this error
./build.x86_64-linux.i586-oe-linux/gcc/cc1plus -Os -march=pentium ios_init.c
and attached is the testcase to reproduce it
Thanks for the Launchpad ticket, Ken. We'll track it through that.
