Question

我在CentOS上的Mono 4.4.1运行时崩溃堆栈跟踪。 Mono是使用configure，make，make install从tarball构建的。有没有办法获得有关正在执行的行号的更多信息，例如在配置步骤中启用标志？

    Native stacktrace:

    mono() [0x4ac038]
    /lib64/libpthread.so.0(+0xf100) [0x7efc4ff11100]
    /lib64/libc.so.6(gsignal+0x37) [0x7efc4f95f5f7]
    /lib64/libc.so.6(abort+0x148) [0x7efc4f960ce8]
    mono() [0x63e96e]
    mono() [0x63e75b]
    mono() [0x63e8bc]
    mono() [0x636332]
    /lib64/libpthread.so.0(+0x7dc5) [0x7efc4ff09dc5]
    /lib64/libc.so.6(clone+0x6d) [0x7efc4fa20ced]

    Debug info from gdb:
    Got a SIGABRT while executing native code. This usually indicates
    a fatal error in the mono runtime or one of the native libraries
    used by your application.

您需要安装gdb才能在堆栈跟踪的输出中获取行号，如下所示。
