System Configuration
---------------------
Architecture (example: Intel Pentium) : Intel Pentium
Operating System (example: Linux 2.0.26 ELF) : Linux 2.2.7 ELF
Distribution : SuSE 6.1
PostgreSQL version (example: PostgreSQL-6.5.1): PostgreSQL-6.5.1
Compiler used (example: gcc 2.8.0) : egcs-2.91.66
Please enter a FULL description of your problem:
------------------------------------------------
Following error seems to occur only on Linux with libc.so.2.0.7 (libc-6).
While preprocessing a particular file with 'ecpg', the preprocessor crashes
with a segmentation fault (signal 11). I tried to trace down the problem
and found that it must be into libc library. However. I'm not so sure about
this. The problem occures here only with one particular file. This file is
attached to this mail.
I rebuild 'ecpg' with debugging options enabled. Following is the backtrace
of the debugger 'gdb':

Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
Try to preprocess the attached file with 'ecpg'. You should have
libc.so.2.0.7 installed and you should try it on an Intel Pentium.
I tried the same on Solaris 2.6 x86 and it worked well. No problems!
I hope this error is reproduceable on an other system too. Have no other
Linux here to try.
If you know how this problem might be fixed, list the solution below:

Sorry no fix known.
