What would cause this kind of output from the debugger? All of the files that are said to be unable to have their symbols read [bottom paste] seem to be in the right place on my disk. When I run under the graphical debugger on OS X, breakpoints in the main program are ignored and the call stack is all blank lines except for level 7 which is denoted as ?? (two question marks). When I try a backtrace in the regular debugger (noob alert), I get, among others,
#4 $000420c8 in _p_Read_Line (F=$1df000) at /Users/adriaan/gnu/gpc/ gpc344d2/gcc-3.4.4/gcc/p/rts/files.pas:2297
which is indicated as being called from my program, except that my program doesn't call anything like readline and why is there an indication that there is something interesting at /Users/adriann/ ? My program sort of hangs at this point, but indeed it continues if I press Return.
Here's the intial debugger output:
