Bug #18239 2011-07-15 10:45

petschy

Build hangs with 100% cpu usage

This happens only now and then, building the same automake based project.

The UI is not responsive, have to kill the process by hand and the project changes are lost, unfortunately, so the end result is very similar to a crash.

The platform is Debian/Squeeze/AMD64, gcc version is 4.6.1, codeblocks was built from svn-7280 (I will try the current 7286, too).
 
There are two dead processes, according to top:
4619 petschy   20   0     0    0    0 Z    0  0.0   0:00.01 make <defunct>
5792 petschy   20   0     0    0    0 Z    0  0.0   0:00.00 g++  <defunct>

Attached to the process from gdb, the stack trace is:

When stopped again, the trace is a little different:

#0  0x00007f341bc636b6 in wxPipeInputStream::CanRead() const () from /usr/lib/libwx_baseu-2.8.so.0
#1  0x00007f341c4efc02 in wxGUIAppTraits::WaitForChild(wxExecuteData&) () from /usr/lib/libwx_gtk2u_core-2.8.so.0

#5  0x00007f34054f15ad in NativeParser::GetGCCCompilerDirs (this=<value optimized out>, cpp_compiler=...) at nativeparser.cpp:1079

I did more stop/continue cycles, and Yield, CanRead and WaitForChild were at the top of the call stack.
