ASSERTION: Invalid computed height: 'aComputedHeight >=0'
nsHTMLReflowState.cpp, line 251
NS_PRECONDITION(aComputedHeight >= 0, "Invalid computed height");

The above assertion happens every time I interact with the UI (new windows or controls).

Bellow is my .mozconfig. I want to test Thunderbird as a PIM (+Lightning):

ac_add_options --enable-application=mail
ac_add_options --enable-calendar
ac_add_options --disable-optimize
ac_add_options --enable-debug
ac_add_options --disable-javaxpcom
mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/tbird-debug
mk_add_options MOZ_CO_PROJECT=mail

From my $HOME folder:
hg clone http://hg.mozilla.org/comm-central/ src
And inside src:
python client.py checkout
make -f client.mk build

To get a fresh build I am doing (inside source):
python client.py checkout
make -f client.mk build

I am using:
1)VS2005Prof+SP1+updatetoVista
2)Vista Home Premium SP1
3)Latest Vista SDK
4)start-msvc8.bat

I set %HOME% to C:\mozilla-build\julio inside start-msvc8.bat. This is where .mozconfig is.

I just run C:\mozilla-build\julio\src\tbird-debug\mozilla\dist\bin\thunderbird.exe to test it.

There are other assertions but "Invalid computed height" is far common.

If I did something wrong, forgive me.

Reproducible: Always

Likely a core bug, but does this happen without lightning installed?

Comment 2

[Júlio Maranhão]

1) I removed the lightning line (ac_add_options --enable-calendar).
2) Deleted everything inside MOZ_OBJDIR.
3) Then checkout (new changes) and build.

That assertion error is GONE!

Instead of step 2 what could I do to clean for a safe rebuild?

Cheers

Moving to Calendar > Build Config, since it seems more fitting.

Comment 4

[Martin Schröder [:mschroeder]]

Probably an underlying core bug, but we have to narrow down where it happens. -> Moving to General because it's no build/config issue.

[Philipp Kewisch [:Fallen][📱📆]]

Does this still happen with the latest 1.0b2pre nightlies?

no response to questions in previous comment, so => incomplete.
if you still see the problem in the newest version, please comment in the bug.
