Subject: [Bug c/45106]  New: casting of variadic function pointers to normal function pointers causes segfaults on 64bit systems
Date: Wed, 28 Jul 2010 11:47:00 -0000	[thread overview]
Message-ID: <bug-45106-19494@http.gcc.gnu.org/bugzilla/> (raw)

Casting a variadic function pointer to normal function pointer (with adequate
number and type of arguments) causes a segfault, when the function is called.
Vice versa (casting normal function pointer to variadic function) works fine.
The problem only occurs for 64bit builds. Casting works nice in all directions
for 32bit builds.
