Intel® Fortran Compiler 17.0 Developer Guide and Reference
Enables or disables stack overflow security checks for certain (or all) routines.
Linux and macOS: | -fstack-protector[-keyword] -fno-stack-protector[-keyword] |
Windows: | None |
keyword |
Possible values are:
|
If no -keyword is specified, option -fstack-protector enables stack overflow security checks for routines with a string buffer.
-fno-stack-protector, -fno-stack-protector-strong |
No stack overflow security checks are enabled for the relevant routines. |
-fno-stack-protector-all |
No stack overflow security checks are enabled for any routines. |
This option enables or disables stack overflow security checks for certain (or all) routines. A stack overflow occurs when a program stores more data in a variable on the execution stack than is allocated to the variable. Writing past the end of a string buffer or using an index for an array that is larger than the array bound could cause a stack overflow and security violations.
The -fstack-protector options are provided for compatibility with gcc. They use the gcc/glibc implementation when possible. If the gcc/glibc implementation is not available, they use the Intel implementation.
For an Intel-specific version of this feature, see option -fstack-security-check.
