The SDCDB clear breakpoint by specifying 'filename:line' command is not working.
The versions of SDCDB with SDCC 3.6.0 and the current SVN head (with [patches:#449] and [patches:#450] applied) have this issue. I have not checked other versions of SDCC.
To reproduce compile the source and debug in SDCDB using the following commands:
sdcc --debug clearbug.c
sdcdb -cpu 8051 clearbug -z -b
Then in sdcdb set and clear the breakpoint.
(sdcdb)break clearbug:13
Breakpoint 1 at 0x81: file clearbug.c line 13
(sdcdb)clear clearbug:13
No breakpoint at address 0x7fffffff
