Is there no way to fix this without renaming? It seems impractical to change bmalloc whenever any client uses the same file name. 1753061 3 kkinnunen 2021-04-21 23:58:13 -0700 I think one alternative is to encode the project name in the .o file, but I couldn't find Xcode options for that. E.g Compiling DebugHeap.cpp would produce libbmalloc-DebugHeap.o.
