Strange glibc detected invalid pointer with gtk_entry

[Herbert Gasiorowski <gasi Mathematik Uni-Marburg de>]

I have an issue with nearly all gtk+ programs: since about one week the programs 
crash at startup with some fault like this:

*** glibc detected *** ./gtk-tab2: munmap_chunk(): invalid pointer: 
0x0000000001aa8eb0 ***
======= Backtrace: =========
/lib64/libc.so.6[0x365a47703a]
/lib64/libglib-2.0.so.0(g_free+0x23)[0x365c449743]

But if I start the program via ssh it runs as expected:
   ssh -X $HOSTNAME myprogram
AND if I link without -lmcheck it is ok too ...

I deleted all code which did not affect this issue:
It is not much more than another Hello World example but using gtk_entry to 
display the text (#if 1):

Fedora 15 and gtk3-3.0.11-1.fc15.x86_64
(gtk2 will fail too)

Can someone tell me what I should do next?
