Re: [csmith-dev] GCC - Internal Compiler Error

Here is the link to the bug reported on GCC Bugszilla.


Here are the options used for building compiler.

sing built-in specs.

gcc version 6.3.0 20170516 (Debian 6.3.0-18+deb9u1)

I used creduce for above file named "crash1.c" to generate reduced code.
Sorry, if I used creduce in wrong way because in reduced code, header file "csmith.h" exists.

Here is the command line below -
gcc -O1 crash1.c -w

Do I need to sent build options which I have used while building compiler?

Can you please send command line options you use?
I can then verify whether the bug is still present.
