回复 2# zhlong8
多谢版主回答!我查了下也确实如版主所说。我想知道这个警告对程序的运行有没有影响?也就是说我是不是可以忽略这个警告啊?
Deep recursion on subroutine "main::spring" at profile line 229,
<IN> line 38577 (#1)
(W recursion) This subroutine has called itself (directly or indirectly)
100 times more than it has returned. This probably indicates an
infinite recursion, unless you're writing strange benchmark programs, in
which case it indicates something else.
This threshold can be changed from 100, by recompiling the perl binary,
setting the C pre-processor macro PERL_SUB_DEPTH_WARN to the desired value. |
