Package: libc6-prof
Version: 2.7-16
Severity: normal
Executables linked with option -p or -pg and profiling library libc_p.a
throw a SIGFPE. Even very simple one as this:
% cat x.c
#include <stdio.h>
main(){printf("hello, world!\n");}
will die:
% gcc -p x.c -lc_p
% a.out
[1] 30461 floating point exception (core dumped) a.out
% gcc -pg x.c -lc_p
% a.out
[1] 30468 floating point exception (core dumped) a.out
% gcc -g -pg x.c -lc_p
% gdb a.out
