Subject: [PATCH] exception_handler.cc: Match the types for SIGSTKSZ
|
|
In glibc 2.34, SIGSTKSZ is a syscall which returns a long int, therefore
|
current check fails
|
|
| ../git/src/client/linux/handler/exception_handler.cc:141:49: error: no matching function for call to 'max(int, long int)'
|
| 141 | static const unsigned kSigStackSize = std::max(16384, SIGSTKSZ);
