gdb on osf1 acting weird with breakpoints

[Ludo Gorzeman]

hi all,

for some reason gdb refuses to break on breakpoints in libc twice in a
row.. check this:

csh> gdb ./test_gdb

(gdb) break *0x3ff8019ac00
Breakpoint 1 at 0x3ff8019ac00

Breakpoint 2 at 0x120001198: file test_gdb.c, line 6.

(gdb) info breakpoints
