Bug 119017

Description of problem:

Certain size files cause gawk to abort with error.  Once the file
meets a certain size, gawk seems to work fine.

Steps to Reproduce:

Example here with a comment-only file (for simplicity sake):

$ cat test1.awk
#################################################################
#################################################################

$ wc test1.awk
      9       9     594 test1.awk
$ /usr/bin/awk -f test1.awk
$ cat test2.awk

$ wc test2.awk 
      8       8     528 test2.awk
$ /usr/bin/awk -f test2.awk 
awk: test2.awk:9: fatal error: internal error
Aborted

I can not reproduce this error:

$ wc test1.awk
  9   9 594 test1.awk
$ wc test2.awk
  8   8 528 test2.awk
$ /usr/bin/awk -f test1.awk 
$ /usr/bin/awk -f test2.awk 
$ $ rpm -q gawk
gawk-3.1.3-7
$

Can you send me the debug output of "/usr/bin/awk -f test2.awk", please?

Let me know if you expected more info than this:

Please update prelink to the fc2 version and try again.

Please reinstall gawk, there seems to be a big problem with it.

"rpm -V gawk" may not report anything.

To get rid of the prelink warnings, please install the fc2 prelink
package.

Installed fc2 gawk:

# rpm -ivh --force /mnt/Fedora/RPMS/gawk-3.1.3-7.i386.rpm
...
$ rpm -q gawk
gawk-3.1.3-7
# rpm -V gawk

Debugging for new gawk:

fc2 prelink is requring me to install/upgrade too many other packages:

# rpm -Uvh prelink-0.3.1-2.i386.rpm
warning: prelink-0.3.1-2.i386.rpm: V3 DSA signature: NOKEY, key ID
30c9ecf8
error: Failed dependencies:

30c9ecf8
error: Failed dependencies:
        libc.so.6(GLIBC_2.3.4) is needed by libselinux-1.6-3

I have rechecked this with FC1 (glibc-2.3.2-101 and gawk-3.1.3-3 or
gawk-3.1.3-7), but I can not reproduce the problem at all.

Closing.
