Automated Code Analysis

cppcheck analysis of tcc_0.9.25-6.dsc

• ./examples/ex2.c:90 [error] - Array 'stack_res[60]' index -3 out of bounds
• ./i386-asm.c:942 [error] - Array 'regs_allocated[8]' index 8 out of bounds
• ./lib/bcheck.c:147 [error] - Null pointer dereference
• tccpp.c:2757 [error] - Dangerous assignment - function parameter takes the address of a local auto-variable. Local auto-variables are reserved from the stack. And the stack is freed when the function ends. So the pointer to a local variable is invalid after the function ends.
• ./tccpe.c:887 [error] - Resource leak: op
• ./tests/boundtest.c:26 [error] - Buffer access out-of-bounds: tab
• ./tests/boundtest.c:99 [error] - Buffer access out-of-bounds: tab
• ./tests/boundtest.c:69 [error] - Buffer access out-of-bounds
• ./tests/boundtest.c:86 [error] - Buffer access out-of-bounds
• ./tests/boundtest.c:126 [error] - Buffer access out-of-bounds: tab
• ./tests/boundtest.c:148 [error] - Buffer access out-of-bounds: tab
• ./tests/boundtest.c:158 [error] - Deallocating a deallocated pointer: ptr
• ./tests/boundtest.c:54 [error] - Data is allocated but not initialized: tab4
• ./tests/boundtest.c:69 [error] - Data is allocated but not initialized: tab4
• ./tests/boundtest.c:86 [error] - Uninitialized variable: tab4
• ./tests/boundtest.c:114 [error] - Uninitialized variable: tab
• ./tests/boundtest.c:126 [error] - Uninitialized variable: tab
• ./tests/boundtest.c:138 [error] - Uninitialized variable: tab1
• ./tests/boundtest.c:158 [error] - Uninitialized variable: ptr
• ./win32/tools/tiny_libmaker.c:267 [error] - Common realloc mistake: "anames" nulled but not freed upon failure
• ./win32/tools/tiny_libmaker.c:272 [error] - Common realloc mistake: "afpos" nulled but not freed upon failure
