I recently installed R12B-3 on my eeePC (Linux). When starting the debugger it exits as soon as I use the mouse to navigate. Using the keyboard is ok.
The error surfaces in dbg_ui_mon_win, handle_event, as badarith
my short resaerch on the the mailing lists found a similar error somewhere in the July 2003 Archives as topic "compiler and debugger bugs, R9B-1, Windows XP Home Edition" (second item) but was not answered.
After digging into the code I found that the error must occur when handling the 'motion' event. Finally with some tracing I found out that gs:read(Win, x) and gs:read(Win,y) returns {error, "can't read \"h\": no such variable"} -- (Why 'h' when it asks for x?)
But it will occur only if the window is attached to the left screen border (or maximized). if detached the error will not occur and returns correct window coordinates.
Because on my home (XP) and office workstations (Vista) the debugger is working fine, I suspect something platform dependent, like missing or incompatible packages.
What packages is 'gs' depending on?
Any hints will be appreciated.
