__attribute__ ((nothrow)) seems to be causing the problems.

First, cd into the problem directory, then -E regex.c using same options/flags:

$ cd gettext-0.20.1/gettext-tools/libgrep
$ gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I..  -I.. -I../gnulib-lib
-I../gnulib-lib -I../intl -DIN_GETTEXT_TOOLS_LIBGREP=1
-I/usr/local/include -DNDEBUG  -g2 -O2 -fPIC -pthread -E regex.c >
regex.ii.txt

Second, grep on the throw:

$ grep -B 2 -A 2 throw regex.ii.txt > regex-grep.txt
$ cat regex-grep.txt
extern int isalnum (int) __attribute__ ((__nothrow__ ));
extern int isalpha (int) __attribute__ ((__nothrow__ ));
extern int iscntrl (int) __attribute__ ((__nothrow__ ));
extern int isdigit (int) __attribute__ ((__nothrow__ ));
extern int islower (int) __attribute__ ((__nothrow__ ));
...

I attached regex-grep.txt because it is small. I can attach
regex.ii.txt , but it is 570K.
