Petsc不显示错误发生的位置

没有Petsc，我可以看到哪些文件，哪些函数以及哪条错误发生并传播。随着Petsc，我总是收到相同的错误信息。Petsc不显示错误发生的位置

Petsc中是否有我失踪的标志？

谢谢。

您可以将此问题发布到PETSc用户邮件列表。 http://www.mcs.anl.gov/petsc/petsc-2/miscellaneous/mailing-lists.html – smilingbuddha 2011-05-15 19:30:08

您的代码已经非法访问内存产生SEGV，大概。正如错误消息所建议的那样，您应该使用valgrind或gdb来运行，这将允许您查看堆栈。
