Hi, while trying to get TinyCC to link to Debian sid's armel libraries, I've encountered a problem with weak symbols. The situation is as follows:
- crti.o contains a R_ARM_PLT32 and R_ARM_GOT32 relocation to the weak undefined symbol __gmon_start__ - no library defines this symbol - TinyCC compiles this to an application containing two STB_WEAK SHN_UNDEF symbols __gmon_start__, one with value 0 and one with the offset of the PLT entry as value - libgcc_s.so.1 contains a STB_WEAK SHN_UNDEF symbol __gmon_start__ - when the application is run, libgcc_s.so.1 is given the address of the PLT entry in the application as value of __gmon_start__ - SIGSEGV When linking with GNU ld there is only one STB_WEAK SHN_UNDEF __gmon_start__ with value 0.
