796526 - Debug builds spew "### ERROR: SymGetModuleInfo64: The specified module could not be found." messages

Status: RESOLVED FIXED

(Core :: XPCOM, defect)

Description

[Mark Hammond [:markh] [:mhammond]]

I just ran a debug build of FF, let it sit there for 3 minutes and closed it.  This resulted in over 1300 occurrences of the message "### ERROR: SymGetModuleInfo64: The specified module could not be found." to be printed.  The message seems useless - maybe printing it once would make sense, but given no other details are available and no action can be taken to make it stop, the message should just die.

It is also possible this impacts TBPL builds, where the message "Output exceeded 52428800 bytes, remaining output has been truncated" is common (eg, https://tbpl.mozilla.org/php/getParsedLog.php?id=15707176&tree=Mozilla-Inbound)

I kinda guessed the component and possible reviewer - please reassign if I got it wrong!

This looks fine, but let's ask dbaron to take a look as well.

ok, I suppose.  Seems bad that it's failing, given the comments, though.

Yeah - I suspect the address end up being in Windows modules where symbolic information isn't available - or something like that :)  It seems to be working OK for all "our" modules.
