Sun 29 Mar 2015 09:13:11 AM UTC, comment #3: A patch is submitted to the mob: fix for the bcheck.o (bug #14958) And a segmentation fault must be happend when v[10] = 0; This is desired behavior: we use an invalid pointer to catch a bug early. A debugger can show an error point in the program.	Sergey Korshunoff <seyko>
Fri 19 Oct 2012 03:17:19 PM UTC, comment #2: I believe the second issue posted was related to STT_GNU_IFUNC relocations missing in tcc. This has already been fixed.	Thomas Preud'homme <robotux>
Tue 19 Oct 2010 10:15:11 AM UTC, comment #1: related problem ? linux 2.6.35-22-generic tcc version 0.9.25 #include <stdlib.h> #include <stdio.h> #include <string.h> int main(int argc, const char argv[]) { char pollo= "ppooo"; printf("%s", pollo); return 0; } calling tcc -b (mem/ptr bounds checker) fails : tcc: undefined symbol 'memset' tcc: undefined symbol 'memmove' tcc: undefined symbol 'memcpy' whitout -b, it works fine. why ?

Fri 11 Nov 2005 06:01:45 PM UTC, original submission: Example (test.c): #include <stdio.h> int main () { int v[10]; v[10] = 1; /* Enforcing a seg-fault here ... */ printf ("v has %d elements.\n", sizeof(v) / sizeof(int)); return 0; } When executing `tcc -b -run test.c' the the runtime error message is printed as expected (but the program still aborts with a seg-fault), but when compiling `test.c' (using `tcc -b test.c -o test') and then executing the program `test' (`./test'), the execution leads to the usual `segmentation fault' - much like if `-b' was never supplied to the compiler. (This problem occurs likewise on SuSE-9.x and Debian 3.x .)	Anonymous
