| Subject: [PATCH] nat/linux-ptrace.c: add missing gdb_byte* cast |
| |
| On noMMU platforms, the following code gets compiled: |
| |
| child_stack = xmalloc (STACK_SIZE * 4); |
| |
| Where child_stack is a gdb_byte*, and xmalloc() returns a void*. While |
| the lack of cast is valid in C, it is not in C++, causing the |
| following build failure: |
| |
| ../nat/linux-ptrace.c: In function 'int linux_fork_to_function(gdb_byte*, int (*)(void*))': |
| ../nat/linux-ptrace.c:273:29: error: invalid conversion from 'void*' to 'gdb_byte* {aka unsigned char*}' [-fpermissive] |
| child_stack = xmalloc (STACK_SIZE * 4); |
| |
| Therefore, this commit adds the appropriate cast. |
