Compiling OpenSAF with gcc 9.2.1 gives errors. Most of these errors are due to
uses of strncpy, strncat, etc. The compiler is complaining about possible
string operation overflows. Here is an example:
In file included from /usr/include/string.h:494,
from src/imm/tools/imm_import.cc:26:
In function 'char* strncpy(char*, const char*, size_t)',
inlined from 'void charactersHandler(void*, const xmlChar*, int)' at
src/imm/tools/imm_import.cc:1856:18:
/usr/include/bits/string_fortified.h:106:34: error: 'char*
__builtin_strncpy(char*, const char*, long unsigned int)' specified bound
depends on the length of the source argument [-Werror=stringop-overflow=]
106 | return __builtin___strncpy_chk (__dest, __src, __len, __bos (__dest));
| ~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
src/imm/tools/imm_import.cc: In function 'void charactersHandler(void*, const
xmlChar*, int)':
src/imm/tools/imm_import.cc:1846:34: note: length computed here
1846 | size_t oldsize = strlen(state->attrValueBuffers.front());
| ~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
