Bug ID: 87525
Summary: infinite loop generated for fread() if enabling -flto
Product: gcc

When trying to compile flac with -flto enabled, it seems to generate an
infinite loop when the source code is calling fread();
If i remove the -flto flag, the generated code is no longer an infinite loop.
You can find in attachment a screenshot of the gdb screen with the faulty code.
Notice the loop at address 0xb7d16980
Also attached output of gcc -v -save-temps
