All this happens on WinXP home (SP2) using djdev204 beta 1 and bash205b.
When I run the testsuite of today's bison's cvs sources I get the following
error output:

4. input.at:89: testing ...
input.at:148: bison input.y


malloc: subst.c:5769: assertion botched

malloc: block on free list clobbered

If I run the testsuite directly from the msdos prompt with the command:
  sh testsuite
the testsuite runs flawless.
Any ideas what is wrong here? If more informations is need, please contact me.
