Segmentation fault with option "--C6Run:replace_malloc "

huang jack

i'm using "dvsdk_omapl138-evm_04_03_00_06", i run c6runlib demo in folder "test", they are ok, but when i run c6runlib demo in folder "examples", program crash and got "Segmentation fault", i found if add "--C6Run:replace_malloc " to "C6RUN_ARFLAGS", crash will happen, even there is no "malloc" on dsp side, any one encounter this ?

HI Huang,

Please refer to Daniel`s response here to see what components of C code are affected with the use of the "replace_malloc" option. Does your code use any of those APIs in the code?

You might also want to make sure that apart from the source code you are passing to the c6run lib, if any of the other libraries being linked to the application use any of those APIs.

Regards,

Rahul

thanks, Rahul

how to make sure i'm using the correct libraries? i just change the makefile under "c6run_0_98_03_03\test\c6runlib\c6x_intrinsics", c6run_ar option from "C6RUN_ARFLAGS=rcs" to "C6RUN_ARFLAGS=rcs --C6Run:replace_malloc", and i run demo under "c6run_0_98_03_03\examples\c6runlib" all fail ed.
