我用java jnative调用dll, 前面几个接口都是使用正常的.
但是有个接口调用过之后,会抛个异常,如下:
An unrecoverable stack overflow has occurred.
#
# An unexpected error has been detected by HotSpot Virtual Machine:
#
# EXCEPTION_STACK_OVERFLOW (0xc00000fd) at pc=0x0da1db27, pid=444, tid=580
#
# Java VM: Java HotSpot(TM) Client VM (1.5.0-b64 mixed mode, sharing)
# Problematic frame:
# C [VodCltApi.dll+0x1db27]
#
# An error report file with more information is saved as hs_err_pid444.log
#
# If you would like to submit a bug report, please visit:
# http://java.sun.com/webapps/bugreport/crash.jsp
========= 但是这个接口我用VC调用是正常的.不知道是哪里出了问题.
