Hello.
I don't know how to report this bug, but I have the following
situation. I compile my program with "-fsanitize=undefined". My
program is a compiler. After that I start compiling the 465.tonto
SPEC. And while compiling it I get the following error:
==19735==ERROR: UndefinedBehaviorSanitizer failed to deallocate
0x100000 (1048576) bytes at address 0x7f25c1b00000
==19735==Sanitizer CHECK failed:
../../../../src/libsanitizer/sanitizer_common/sanitizer_posix.cc:133
(("unable to unmap" && 0)) != (0) (0, 0)
My gcc is:
x86_64-none-linux-gcc --version
x86_64-none-linux-gcc (GCC) 6.0.0 20151018 (experimental)

(2015-04-24) x86_64 GNU/Linux
This bug is reproducable with stable gcc-5 on debian system. To my
pity I can't give you the binary or source of my compiler, but I can
try to get information you need to fix this bug
