Bug #: 52615
Summary: function pointer casting bug
Classification: Unclassified
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: cglb...@gmail.com
gcc compiler can't create any working code for my programm.
Full programm here:
int a(char x)
{
return x;
}
int main()
{
float result;
result = (*(float (*)(double, int, char *))a)(4.5f, 7, "Hello");
return 0;
}
gcc input:
gcc main.c
gcc output:
main.c: In function 'main':
main.c:10:48: warning: function called through a non-compatible type [enabled
by
default]
main.c:10:48: note: if this code is reached, the program will abort
Compiler create executable file. But it doesn't work.
Other compilers(g++, MSVC 10) works fine. No warnings and working programm.
