Description Vladimir Kondratiev 2005-03-07 22:58:53 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6)
Gecko/20050223 Firefox/1.0.1

Description of problem:
While rebuilding RPM for esvn 0.6.9 (from
http://esvn.umputun.com/esvn-0.6.9-1.src.rpm),
ui segfaults.

Even if .ui file that was compiled, is incorrect, 'ui' should provide
error message but not segfault.

Version-Release number of selected component (if applicable):
qt-3.3.4-9

How reproducible:
Always

Steps to Reproduce:
1. cd /tmp && wget http://esvn.umputun.com/esvn-0.6.9-1.src.rpm
2. rpmbuild --rebuild esvn-0.6.9-1.src.rpm


Actual Results:  ui segfaults (just last few lines):

RPM build errors:

Expected Results:  compilation went OK

Additional info:

Comment 1 Than Ngo 2005-03-09 10:11:06 UTC

it seems a bug in kdelibs (libkdeui), which caused the Segmentation fault.

Comment 2 Petr Rockai 2005-03-09 10:25:34 UTC

Assigning to self.

Comment 3 Petr Rockai 2005-03-18 06:54:32 UTC

Was tracked down to a possible glibc bug. I suggest using -nounload switch 
with uic in the meantime, as it remedies the problem. It is an workaround for 
the long-problematic library unmapping code within glibc.

Comment 5 Ville Skyttä 2005-03-18 16:37:52 UTC

Happened also when building qascade from Extras, -nounload worked around it.

Comment 6 Vladimir Kondratiev 2005-03-20 08:25:59 UTC

I confirm -nounload works.
I modified QMAKE_UIC line in /usr/lib/qt-3.3/mkspecs/default/qmake.conf to
QMAKE_UIC		= $(QTDIR)/bin/uic -nounload
till glibc fix, this should fix this issue

Comment 7 Than Ngo 2005-03-21 08:55:54 UTC

it's fixed in glibc-2.3.4-16, which should be available in rawhide now.

Comment 8 Ville Skyttä 2005-03-21 19:43:13 UTC

Yep, at least qascade seems to build fine without -nounload to uic now.  Thanks.

Comment 9 Vladimir Kondratiev 2005-03-22 08:10:18 UTC

My case get fixed too.
