Assigned to the one responsible for the alpha project. I looked into this a bit.
I can't reproduce it. For me, gdb doesn't crash but instead xosview does:
[ ... ]
Reading in symbols for dl-init.c...done.
Reading symbols from /lib/libnss_files.so.2...done.
Reading in symbols for malloc.c...done.
Program received signal SIGSEGV, Segmentation fault.
0x2000034dae4 in chunk_free (ar_ptr=0x20000424ac0, p=0x120047900)
at malloc.c:3228
3228 malloc.c: No such file or directory.
in malloc.c
Current language: auto; currently c
Could you perhaps debug gdb with itself and get a stack trace of the crash?
That might help. Thanks.
I can not reproduce this problem, please close this item. --George |
