gdb 调试任何程序都提示 “Program received signal SIGTRAP, Trace/breakpoint trap.”

[jack_ooneil]

不知道什么原因导致的GDB出现这个问题。

以前GCC和GDB版本都比较低， 为了支持C++11我升级了GCC 到5.3.0版本， GDB升级到了7.11版本， 都是编译安装的。
编译helloworld 都出现这个信号，有谁遇到过这中问题吗？谢谢

@r_Jimy 这个帖子我也看到过，但是好像没效果。 Program received signal SIGTRAP, Trace/breakpoint trap. 0x00367793 in _dl_debug_state () from /lib/ld-linux.so.2 (gdb) info registers eax 0x0 0 ecx 0x37363c 3618364 edx 0x3590d4 3510484 ebx 0x372fc0 3616704 esp 0xbfffc060 0xbfffc060 ebp 0xbfffc060 0xbfffc060 esi 0x373650 3618384 edi 0x37363c 3618364 eip 0x367793 0x367793 <_dl_debug_state+3> eflags 0x346 [ PF ZF TF IF ] cs 0x73 115 ss 0x7b 123 ds 0x7b 123 es 0x7b 123 fs 0x0 0 gs 0x0 0 (gdb) set $ps&=~(1<<8) (gdb) info registers eax 0x0 0 ecx 0x37363c 3618364 edx 0x3590d4 3510484 ebx 0x372fc0 3616704 esp 0xbfffc060 0xbfffc060 ebp 0xbfffc060 0xbfffc060 esi 0x373650 3618384 edi 0x37363c 3618364 eip 0x367793 0x367793 <_dl_debug_state+3> eflags 0x246 [ PF ZF IF ] cs 0x73 115 ss 0x7b 123 ds 0x7b 123 es 0x7b 123 fs 0x0 0 gs 0x0 0 (gdb) continue Continuing.

试试 handle SIG5 nostop pass

[jack_ooneil]

@zhxianbin 也不行 (gdb) start Temporary breakpoint 1 at 0x8048c46: file 12-1main.cpp, line 23. Starting program: /home/lpf/cpp/chapter12/a.out Program received signal SIGTRAP, Trace/breakpoint trap. 0x00367793 in _dl_debug_state () from /lib/ld-linux.so.2 (gdb) handle SIG5 nostop pass Unrecognized or ambiguous flag word: "SIG5".

[zhxianbin]

这就不明白怎么回事了

楼主解决了么?

[heronism]

也遇到同样的问题了，楼主解决了说一下啊

[JoeBlackzqq]

哎，我也莫名的遇到了。果断去除所有断点，然后重新添加断点，解决！ 可能是由于原先下完断点后，代码又编辑过，导致断点对应的行号对不上了，猜测！
