(this is with VC9 express on windows vista)

Yeah, I had the same thing (VC9 on Vista). Happened the first time (clean build with -j3) but went fine the next, still with -j3.

Same here with the identical configuration. It worked fine on a second try yesterday. But now it stopped again after a hg pull and hg update.

This patch uses a single (constant-named, even) PDB file for all compiled files, and a separate PDB file is generated by the linker for the final DLL or program.

Comment on attachment 346326 [details] [diff] [review] Use a separate PDB for compiled files and for the final library/program, rev. 1 # make builds on Windows. Now we just write to a pdb file per compiled file. # See bug 286179 <https://bugzilla.mozilla.org/show_bug.cgi?id=286179> for # details. -- chase@mozilla.org Can you kill this outdated and no-longer-correct comment? Otherwise looks fine. Do you want to make the same COMPILE/LINK distinction for HOST_PDBFILE?

Pushed http://hg.mozilla.org/mozilla-central/rev/5d832205b7fb The distinction mainly exists for performance reasons, and since host-compiles are uncommon we can just leave them in the slow path (separate PDB for each object file).
