在 MinGW GCC 4.4.1 和 4.5.0 上,我都是用 test.cpp 能跑通,但被 BitcoinMiner 调用时就 SIGSEGV。所以现在看来不是 GCC 版本的问题,而是别的什么,可能就是栈对齐的运气。
On both MinGW GCC 4.4.1 and 4.5.0 I have it working with test.cpp but SIGSEGV when called by BitcoinMiner. So now it doesn't look like it's the version of GCC, it's something else, maybe just the luck of how the stack is aligned.
在 Ubuntu 32 位的 GCC 4.3.3 上我这边运行正常。
I have it working fine on GCC 4.3.3 on Ubuntu 32-bit.
我找到了 MinGW 4.5.0 上 Crypto++ 的问题。这是对应的补丁:
I found the problem with Crypto++ on MinGW 4.5.0. Here's the patch for that:
