Description asmwarrior 2011-06-05 01:56:59 UTC 
I build a gdb-7.3.50.20110604 cvs gdb version under MinGW and MSYS.

But when debugging, gdb failed to set a breakpoint, it seems it failed to handle the windows style file path.

look at the log:

> break "E:/code/cb/cb_trunk/src/plugins/codecompletion/parser/parserthread.cpp:524"
No source file named E.
Breakpoint 2 ("E:/code/cb/cb_trunk/src/plugins/codecompletion/parser/parserthread.cpp:524) pending.
>>>>>>cb_gdb:

You see, "No source file named E.", this is the error message.

the gdb 20110401 cvs snapshot build works quite well on setting breakpoints. 

I found that the change in linespec.c in
http://sourceware.org/ml/gdb-cvs/2011-05/msg00255.html
and
http://sourceware.org/ml/gdb-cvs/2011-05/msg00196.html

maybe cause this issue.

If I replace the linespec.c with an old version of linespec.c before May 24, 2011, then gdb build 20110604snapshot can correctly set breakpoints under Windows.
