Re: [Tinycc-devel] [PATCH] Re: using gdb 6.6 on linux fail after dec18 2013

Yes, you are right. I'm lost the ground trying to detect a point after
which  debugger don't do the work. tcc v0.9.25 was working. After a
grischka patch a debugger don't work. And exactly with the same
symptom: gdb refused to know "main".I don't understand why, sorry. Did
gdb work for you w/o a patch?

PS: may be this is because I work in 32bit environment...
