Preprocessed source file
On my x86_64-pc-linux-gnu, Slackware64 14.2, running a custom installation of
GCC 8.2.0, under the stock Slackware package glibc-2.23-x86_64-2_slack14.2, I
get a C compiler crash when compiling the following source:
/* demo.c */
#include <complex.h>
int
main (void)
{
double complex E = catan(CMPLX(0.5, 0.6));
return 0;
}
/* end of file */
with the command line:
gcc -v -save-temps -c -o demo demo.c
The package GCC is compiled with:
$ /path/to/gcc-8.2.0/configure \
--prefix=/opt/gcc/8.2.0 \
--enable-languages=fortran,c,c++ \
--disable-multilib
The output of the compiler command is:
>> gcc -v -save-temps -c -o demo demo.c
Using built-in specs.
