Thanks for the quick response. Unfortunately, I'm not familiar with src/intervals.c and I doubt if it is easy to split it up... But, to answer your suggestion, I forgot to mention that I could reproduce the problem with "-g -O" and "-g -O1". Following your suggestion, I also tried "-g -O1 -fno-unit-at-a-time" on src/intervals.c and the problem remains (the breakpoint is hit). The breakpoint is not hit with "-g -fno-unit-at-a-time" (or with "-g", as I originally reported). Does this help? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35249
