[fpc-devel] Problem with compilation (unknown crash)

[Michel Catudal]

Is there a way to figure out when a crash occurs, in other words get the compiler to tell me the conditions that made it crash the compilation?
I am able to create a compiler but it looks like it barfs when trying to create the RTL stuff, it is kind of hard to fix if I don't know what causes the crash.

Here is a part of the last messages :

The command used to compile is the following :

PP=ppcx64 make buildbase OS_TARGET=embedded CPU_TARGET=avr32 CROSSOPT=-O-

This is on a Scientific Linux 6.2 platform
