Re: Internal compiler error while compiling gcc 7.1.0

Thanks Jonathan for your help!

It now compiles without problems.

However, when I run make -k check it get stuck for several hours at:

Running 
/home/hector/dwnld_prog/gcc-7.1.0/gcc/testsuite/gcc.dg/tree-ssa/tree-ssa.exp 
...
Running 
/home/hector/dwnld_prog/gcc-7.1.0/gcc/testsuite/gcc.dg/tsan/tsan.exp ...
WARNING: program timed out.

When I manually stop the program I get this summary:

got a INT signal, interrupted by user

                === gcc Summary ===

# of expected passes            105253
# of unexpected failures        311
# of unexpected successes       22
# of expected failures          199
# of unresolved testcases       2
# of unsupported tests          1611

What could be causing this problem?

Thanks for your help,

Hector
