However, it completely overrides the variable, which causes problems, if the user also needs to define the variable to add other .so files. (Happened in a testing framework I am using). One possible fix: if [[ "${LD_PRELOAD:-UNSET}" = "UNSET" ]]; then add_env="LD_PRELOAD=$memusageso" else add_env="LD_PRELOAD=${LD_PRELOAD}:$memusageso" fi -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
