seg fault in cygwin1.dll during gdb session

[Dierk Bolten]

Hi!

While playing around with an example file of the libxml2 library (2.6.22-1), I ran into problems using the gdb debugger (I used the ddd and insight front-end, but the problem also comes up when invoking gdb (GNU gdb 6.3.50_2004-12-28-cvs (cygwin-special)) directly). The example file (tree.c attached) was compiled using:

gcc `xml2-config --cflags` -g -o tree tree.c `xml2-config --libs` 


when I run tree.exe on an example xml file inside bash it works fine, but when 
I start the program inside gdb (or ddd), gdb receives a sig fault


Program received signal SIGSEGV, Segmentation fault.
0x610ae938 in pthread_key_create () from /usr/bin/cygwin1.dll


at line 82

doc = xmlReadFile(argv[1], NULL, 0);

Does somebody have a clue what is going on? Any help is much appreciated!
Thanks,
Dierk
