Ok, the profiling patch I sent is somewhat wrong - the gcrt0.o should not be linked with cygwin1.dll. However: this call monstartup ((u_long) &eprol, (u_long) &etext); is wrong. The result being that the gmon data fields p->lowpc p->highpc p->textsize are wrong, and the in-cygwin calls to mcount() return without logging the call arc because of the test for frompc > p->textsize. So, if anyone has some idea, on how the gcrt0.o code can be tweaked such that the monstartup call is given the real low and high limits for the object, that'd be great. Rob
