--- Comment #25 from Richard Biener <rguenth at gcc dot gnu.org> ---
How about allocating memory by other means (brk/mmap) instead?  That is, run
your own simple allocator?  I suppose gcov never frees things (until the end)
so it could be quite simple one?  And fall back to static allocated counters
for targets that we do not handle?  Is there a command-line option to
choose "static" counters?

More possibilities involve libdl and dlsym to iterate to 'malloc' from a
different shared object than the one profiled.  Or on glibc platforms use
__malloc instead of malloc (via alias).

That said, using plain 'malloc' was a bad idea.
