-Beschreibung:
-Bug 290526 Write separate PDBs for test OBJs r=glandium
-
-Quite often when running a parallel NSS build, I get the following
-compiler error message, resulting in a build failure, despite
-compiling with the -FS flag:
-
-.../nss/nspr/pr/tests/zerolen.c: fatal error C1041:
-Programmdatenbank "...\nss\nspr\out\pr\tests\vc140.pdb" kann nicht
-ge<94>ffnet werden; verwenden Sie /FS, wenn mehrere CL.EXE in
-dieselbe .PDB-Datei schreiben.
-
-The failing source file is always one of the last test object
-files. But the actual problem is not the compiler accessing the
-PDB file, but the linker already linking the first test
-executables accessing the shared PDB; at least that's my guess.
-
-So instead of using a shared PDB for all test object files, this
-uses -Fd$(@:.$(OBJ_SUFFIX)=.pdb) to write a separate PDB for every
-test's object file. The linker works fine with the shared OBJ PDB.
