[Crash-utility] [PATCH 2/3] tools.c: do not use keywords 'nullptr' as a variable in code
Without the patch:
tools.c: In function ‘drop_core’:
tools.c:6251:23: error: expected identifier or ‘(’ before ‘nullptr’
6251 | volatile int *nullptr;
| ^~~~~~~
tools.c:6259:17: error: lvalue required as left operand of assignment
6259 | nullptr = NULL;
| ^
tools.c:6261:21: error: invalid type argument of unary ‘*’ (have ‘typeof (nullptr)’)
6261 | i = *nullptr;
| ^~~~~~~~
make[6]: *** [Makefile:345: tools.o] Error 1
Note: this was observed on gcc version 15.0.1
