Could be some bug in your glibc on that system?  Otherwise, how come
no one else sees such fundamental problems?

In any case, bugs in memory allocation need to find the code which
corrupted the data structures used by malloc, which happened somewhere
else in the code.  Maybe try running under valgrind (see the advice in
etc/DEBUG under "Running Emacs built with malloc debugging packages").
