Hi there,

I was trying to build a gcc cross toolchain for v850-elf. Following
the advices on http://ecos.sourceware.org/build-toolchain.html,
unfortunately, I failed compiling the gcc with the following error
message:

I tried to solve the problem with the 'poisoned "malloc"' by applying
the YYMALLOC patches as, e.g., described at http://gcc.gnu.org/ml/gcc/2004-09/msg00927.html.
However, the error persists. Can anyone help? What actually is a
"poisoned" (x){c,m}alloc?

Best,

Stephan
