526991 - "make -s -C mail" causes app to segfault [Regression]

Status: VERIFIED DUPLICATE of bug 525481

(Thunderbird :: Build Config, defect)

Description

[Ben Bucksch (:BenB)]

- Linux
- TB trunk

Reproduction:
1. Fetch a fresh c-c (trunk)
2. Build it
3. Start the build
4. make -s -C mail (in build dir)
5. Start the build
6. make -s
7. Start the build

Actual result:
Step 3 and 7 work
Step 5 fails with a segfault

Expected result:
Step 3, 5 and 7 all work (the same)

Severity:
Critical (crash)
Blocker. Any tiny change I make to chrome needs a "make" (I don't bother with plain files chrome). "make -s -C mail" takes ~5s, "make -s" takes ~1min. Given that I do that *all the time*, this is disruptive for development. => Blocker

It's also a regression: It worked 1-2 weeks ago.

Sorry, with "Start the build", I meant to start the application, i.e.
./mozilla/dist/bin/thunderbird

Actually, even after make -s, the first app start works, but the second segfaults. Without any make -s -C mail involved.
I did a diff -urw of the mozilla/dist/bin/, and they were identical before first, second and third start. After make -s -C mail of course changed 2 jar files, but nothing else.

So, it's *not* the build system. I deleted XUL.mfasl, and that fixed it.
Oh how I hate this XUL.mfasl and xpti.dat. Compare bug 525154.

INVALID
