Hello,
I want to implement some programs using the stdlib library, and then simulating it using modelsim. It compil just fine with the gaisler toolchain, but when i run the simulation, malloc() always return NULL and rand( return the following error message :
assertion "REENT malloc succeeded" failed: file "/opt/ncc-1.0.0-gcc/src/ncc-1.0.0/newlib/newlib/libc/stdlib/random.c", line 76I haven’t tested all the fonction included from stdlib.h, but some seem to function, like atoi().
I think I do not use the right option when compiling, but I do not know which option I am not using correctly. When compiling, I use the same option as the example program (when using make soft) :

For information, I use the noelv_generic design with the single-issued GPP64 configuration.
