Package: gdb
Version: 6.3-6
Severity: normal
Hello,
when trying to debug one of my programs I encountered a case where gdb
crashed on the command "break main" before my programm was even
started. The problem occurs on a powerpc machine.
Since the files are largish, I put them up on my web page instead of
appending them to this mail. The files are
http://seehuhn.de/data/gdb-bug - the binary
http://seehuhn.de/data/gdb-bug.i - the preprocessed source
1) Reproducing the bug. You will probably need the atlas3-base and
libg2c0 packages installed to reproduce this.

2) Regenerating the binary. The binary gdb-bug was compiled from
gdb-bug.i using the following two commands:
[EMAIL PROTECTED] [~/y] gcc -ggdb3 -c gdb-bug.i
[EMAIL PROTECTED] [~/y] gcc -ggdb3 -o gdb-bug gdb-bug.o -lm -llapack -lblas
-lg2c
If you need additional information, please let me know.
I hope this helps,
Jochen
