"glibc" is the GNU library for most of the standard C functions,
like memory allocation.  There is no configuration file that I
know about.  This sounds related to the seeminly random memory
deallocation problem reported in the Linux x86 builds of teqc
for years.  (No known solution.)

Best bet is to try the current development version of teqc for
Linux x86 (attached)

teqc_Lx86d.tar.Z: dynamically-linked
teqc_Lx86s.tar.Z: statically-linked

and see http://ls.unavco.org/pipermail/teqc/2005/000093.html

Let me know whether or not whether either of these work out for you.
